    Air Filter Monitors for Supplied-Air Respirators for Plant Air Lines

    Track the quality of incoming air as it travels from your air line to your respirator. These monitors display air-quality data, including carbon monoxide and water vapor levels, and sound an alarm if the air is unsafe to breathe. They also filter the air three times before it reaches you to remove oil, water, and solid particles.

    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
    Image of Product. Front orientation. Environmental-Monitoring Modules for Development Boards .
    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.

    Remote-Reading Multifunction Chemistry Meters

    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.
    For Testing Conductivity, Salinity, Temperature, and Total Dissolved Solids (TDS)
    Image of Product. Front orientation. Chemistry Meters. Remote-Reading Multifunction Chemistry Meters , For Testing Total Dissolved Solids (TDS).
    Conductivity, salinity, temperature, and total dissolved solids (TDS) meters take four measurements at once. Conductivity measures the concentration of salts, nutrients, chemicals, and other substances. Salinity measures the amount of dissolved salts. TDS determines the contaminant levels. The stainless steel sensor is durable and resists breaking.

    Remote-Reading Multifunction Chemistry Meters with PC Output

    Image of Product. Front orientation. Chemistry Meters. 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.

    Water-Resistant ORP Meters

    Since this oxidation reduction potential (ORP) meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion, it’s often used to determine a solution’s ability to break down contaminants in harsh field conditions. For use with dirty liquids containing heavy metals, sulfides, and harsh chemicals, this meter is often used for wastewater treatment. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a Calibration Solution (not included) and the calibration button to maintain accuracy.

    Water-Resistant TDS Meters

    Since these meters float and have a housing that meets IP67, they won’t be damaged by temporary submersion and have complete resistance to dust. They detect total dissolved solids (TDS) in water, hydroponic solutions, and other clean liquids to determine contaminant levels. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a Calibration Solution (not included) and the calibration button to maintain accuracy.

    Air Particle Counters

    Image of Product. Front orientation. 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.

    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.
