Measures pH, ORP (mV/Rel. mV), and temperature(°C or F). The large display is easy to read even at a distance and features stability indication. The meter includes auto-buffer recognition for both USA and NIST pH buffer sets, automatic or manual temperature compensation, temperature in °F or °C, and display Hold.
Each meter includes a convenient slide-out calibration card for quick reference. All models (except for DO 2700) include an electrode arm and metal bracket which can be easily attached to the left or right side of the meter according to your preference.
pHRange -2.000 to 20.000
mVRange -2000.0 to 2000.0
TemperatureRange 32 to 212°F (0.0 to 100.0°C)
Up to 500-point memory with date-time stamp for GLP
Calibration-due alarm let you know when to recalibrate
Audible alarms alert you when reading fall out of range
Calibrations can be performed quickly and accurately with automatic buffer recognition of U.S. or European buffer sets, with the values stored in the pH/ORP Controller’s nonvolatile memory. A large backlit display on the pH/ORP Controllers provide pH, ORP, and temperature plus the current mA output and relay status.

Waterproof, Portable EC/Resistivity/TDS/NaCl and Temperature Meter with Graphic Display, Expanded Calibration and PC Connectivity. HI 98188 waterproof, portable Conductivity Meter has an expanded conductivity range from 0.001 µS/cm to 400 mS/cm, as well as resistivity and 3 salinity scales.
This meter automatically recognizes the probe type (2 or 4-ring) and allows the user to adjust the nominal cell constant. Choose from 7 memorized standards and obtain up to a 5-point calibration. For salinity (% range), HI 7037 buffer allows you to make a 1-point calibration.

Highly versatile 1000 series pH/ORP controller. Select from three control types. Use on/off control to shut off your pump or valve when your process passes its set points. Use pulse frequency or pulse length proportional control to gradually increase or decrease your pump’s or valve’s response, depending on the amount by which your process has passed the set point.
