Concentration Meters

Also known as refractometers, these measure concentration with two or three drops of a solution. Place your sample on the reflecting prism and look through the eyepiece to view the concentration on the internal scale.

Brix (Sugar) Scale

Concentration meters with Brix (sugar) scale measure sucrose concentration.

0% to 18% Concentration Range and 0% to 90% Concentration Range—Meters with 0% to 18% and 0% to 90% concentration range also measure cutting/grinding coolants, oil/water, cleaning solutions, anodizing solutions, plating/acid baths, and chromating solutions.

Automatic Temperature Compensation (ATC) Range—Concentration meters with automatic temperature compensation standardize readings at 68° F to prevent inaccurate results in fluctuating temperatures.

Air Particle Counters

Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems. The sensor probe detects and identifies particles of six different sizes, helping you confirm that your clean room complies with ISO Class requirements. First, use the zero count filter to establish a baseline before taking a sample. Then, either measure the amount of air particles detected within a set time range or the amount of air particles detected within a certain air volume. Counters store up to 10,000 readings in their internal memory, and you can transfer data to your computer via Ethernet or USB connection—no special software required. Compact, lightweight, and battery powered, these counters are portable and able to operate in tight spaces. They’re CE marked as compliant with European health, safety, and environmental standards.

Density Meters


	Built-In Thermometer

Also known as hydrometers, these measure the density of a liquid compared to the density of water. Pour your liquid into a tall container and immerse the density meter into the liquid until it floats. Take the reading where the surface of the liquid touches the measurement unit on the meter. Heavy liquids sink in water and light liquids float in water.

Specific Gravity Scale—Specific gravity is also known as relative density.

Environmental-Monitoring Modules for Development Boards

Keep equipment running and working conditions safe—these modules add air quality tracker capabilities to your development board. Each module gathers data on air conditions, ranging from temperature and humidity to carbon dioxide or volatile organic compound (VOC) levels. These modules easily connect to boards and other components with Qwiic cords or by soldering.

Modules with Air Quality Sensor

Modules with an air quality sensor identify spikes in VOC levels to track air quality changes. Instead of directly measuring VOCs, they measure how much the VOC level has changed in the last 24 hours.

Take multiple water-chemistry and temperature measurements in hard-to-reach places from up to 3 feet away. Often used in tap water and wastewater, these meters work in both clean and dirty liquids. Automatic temperature compensation standardizes readings to 77° F to prevent inaccurate results in changing temperatures. The data hold function freezes the current reading on the display. For easy viewing, temperature and chemistry measurements appear on the same screen. These meters are IP57 rated, so they resist dust and withstand temporary submersion.

To maintain their accuracy, all have a calibration button and some also come with calibration solutions.

Remote-Reading Multifunction Chemistry Meters with PC Output

Test temperature, chemical concentration, contamination, and salt levels in liquid from up to 6 ft. away, then send the results to your computer for analysis. These meters include a USB cable that transfers up to 1,000 readings. Often used to test water quality, they work on both clean and dirty liquids—from tap water to wastewater. Conductivity tests measure the concentration of salts, nutrients, chemicals, and other substances. Total dissolved solids (TDS) tests report contaminant levels. Salinity tests determine the salt levels in liquid. The sensor is made of stainless steel, so it’s durable and resists breaking. IP67 rated, these meters are dust tight and withstand temporary submersion.

To prevent inaccurate results from changing temperatures, these meters automatically standardize temperature readings at 77° F. Temperature readings appear on screen with other measurements, so you won’t have to scroll through multiple screens. A data hold function freezes the current reading on the display.

To maintain accuracy of the meters, they come with calibration solutions and have a calibration button.

Digital Density Meters


Shown with Syringe	Shown with Filling Tube	Digital Display

Accurately measure the density and concentration of liquids—from salt water to battery acid—no calculating or reading scales required. These meters show readings immediately on their digital display. They only require 2 mL of liquid, less than half of a teaspoon, to take precise measurements. Switch between Specific Gravity, Brix, and other measurement units depending on your sample. These meters have an RFID interface, so you can quickly scan sample IDs on containers to identify liquids. They also have Bluetooth to send data wirelessly to your PC or printer. Store up to 1,200 readings, including sample IDs and time stamps, in their memory.

To measure liquids, these meters come with a filling tube and multiple syringes. Dip the filling tube directly into your sample to draw up liquid, or use a syringe to transfer your sample to the meter.

Designed for the field, these meters are IP54 rated, so they stand up to dust and splashing water.

Lubricant Analysis Kits

Send in samples of your gear box oil or hydraulic oil and get back a full report on the condition of both your lubricant and equipment. The report includes results for wear metals (including ferrography), additive concentrations, particulate and water contamination, and viscosity. Sample results will be emailed to you within three to five business days. If the lab discovers critical conditions, they will call you to provide guidance on how to address the problem. Kit includes six bottles with labels, so you can test multiple samples.

Sanitary Conductivity Sensors

Three-Color Display

Image of Attribute. Front orientation. Contains Annotated. Chemistry Meters. Sanitary Conductivity Sensors.

Often used to save rinse water in beverage and pharmaceutical lines, these sensors test the amount of chemicals, cleaners, and other substances in liquids by measuring how well the liquid conducts electricity. They’re 3-A and European Hygienic Engineering and Design Group (EHEDG) certified, thanks to their design that’s easy to keep clean. Highly polished, they limit where bacteria could grow. They also withstand washdowns with hot water, chemicals, and cleaners common to sanitary lines because of their PEEK probe, stainless steel body, and IP ratings. Their IP ratings also mean they’re dust tight and won’t fail if briefly under water. All are FDA compliant to safely touch food.

These sensors work with 4-20 mA analog output to connect to remote displays and programmable logic controllers (PLCs), making them good for hard-to-reach areas and frequent application changes. This also means they’ll set off alarms and trigger cycles to start and stop in automated systems. With the touchscreen, program each color of the display to alert you to errors, completed cycles, and other events. Both the head and the display rotate to view readings from the best angle.

Highly accurate, these sensors test almost any liquid. They also measure temperature—no need for a separate sensor. To compare readings as temperature changes, they automatically standardize readings at 77° F. All meet European safety standards, since they’re CE marked.

Density Testing Flasks

Accurately measure the density of a liquid based on volume and weight. Also known as pycnometers, these flasks help you compare the specific gravity of a liquid to water. They’re often used for quality control in labs for food and beverage, pharmaceutical, or chemical manufacturing. Made from borosilicate glass, these flasks resist chemicals and won’t expand or contract from temperature changes. Use the included non-mercury thermometer to check the temperature of your sample—it's tested for accuracy, has small increments for precision, and is safe for shipping and handling. You can place these flasks in a constant temperature bath to control the temperature of the liquids inside.

To find the specific gravity of a liquid, divide the weight of the testing liquid by the weight of water at the same temperature.

50 ml Capacity—50 ml flasks help you comply with ASTM D153 testing standards for finding the specific gravity of pigments.
