Easy-Read Bench-Top Multifunction Chemistry Meters
Don’t strain your eyes reading a scale—these bench-top meters indicate exact results on the digital display. For complete resistance to dust and protection from temporary submersion, these meters float and have a housing that meets NEMA 6 and IP67. They're for use with water and other clean liquids. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a Calibration Solution

Water-Resistant Multifunction Chemistry Meters
Clean
Liquids
Test different water-chemistry measurements in dirty, wet conditions. Often used in pools and spas, all of these meters are for use with clean liquids. 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.
IP57 meters are protected from dust and temporary submersion in liquids.
Chlorine, oxidation reduction potential (ORP), and pH meters come with three sensors that each take one chemistry measurement. They 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.
Oxidation reduction potential (ORP), pH, and temperature meters take three measurements. ORP measures the amount of dissolved oxygen in liquids. It determines how efficiently a liquid breaks down contaminants.

ORP Meters
Measure a solution’s oxidation reduction potential (ORP) to determine its ability to break down contaminants. These meters are commonly used to monitor water quality in pools, spas, and other clean liquids. Use a Calibration Solution (not included) and the calibration adjustment screw to maintain accuracy. Meters cannot be sold to Canada due to import regulations.

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. Meters cannot be sold to Canada due to import regulations.

Multifunction Chemistry Controllers
The same controller can actuate equipment based on pH or oxidation reduction potential (ORP). Attach pH and ORP sensors (not included) and set the current measurement type with the selection switch. Controllers turn equipment on or off when the reading reaches the actuation point. They have one control relay and two alarm relays. Relays are SPDT (single pole, double throw) and can be set to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed). Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures.
Controller with LED display is more visible in low-light conditions than controller with LCD display.
