Oxygen Detectors
When your work area has too much or too little oxygen, these detectors alert you with an audible alarm, warning light, and vibrating alarm. You can adjust the high and low alarm trigger points to suit your environment.
A calibration check must be performed on the detector before each use to verify that it is working properly. The check can be performed with the press of a button.
The detector with a nonreplaceable battery should be thrown away at the end of its two-year lifespan.

Ultrasonic Gas Leak Detectors
This detector converts ultrasonic waves to an audible sound so you can find leaks. Unlike typical leak detectors, this unit doesn’t rely only on the presence of a gas to work, making it suitable for a wider range of applications. In addition to gas leaks, it identifies ultrasonic sound caused by failing solenoids, valves, and bearings.
For systems under 10 psi, use the optional ultrasonic sound generator.
High-Visibility Quick-Spot Compressed Gas Leak Detectors
These detectors are fluorescent green. Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs. These noncorrosive, nonflammable detectors find leaks in pipes, tubes, fittings, tanks, and cylinders. They adhere to vertical surfaces. All wash off with water.
Use a UV flashlight for enhanced viewing.

Water-Resistant Dissolved Oxygen Meters
Check the oxygen levels of water and other clean liquids in harsh field conditions. This meter has a housing that meets IP57 for good resistance to dust and protection from temporary submersion. It has automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use distilled water and the calibration button to maintain accuracy.
Remote-Reading pH Meters with PC Output
Transmit pH readings to a PC for analysis. These meters have a sensor on a 6-ft. cable for taking remote readings of water and other clean liquids. They have automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate readings in fluctuating temperatures. Use the included calibration solution and calibration button to maintain accuracy.
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.
These meters cannot be sold to Canada due to import regulations.

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. They cannot be sold to Canada due to import regulations.
To maintain their accuracy, all have a calibration button and some also come with calibration solutions.
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.
