Search for:

EPA approved
Measures atmospheric oxygen (Model 1630 also measures dissolved oxygen)
All controls are programmable from front panel
Electrodes virtually maintenance free - no filling solutions or membranes to change
Dual four-digit LED displays for process variable, set point
Two independent set points (Low-High, High-High, Low-Low)
Auxiliary alarm point
Optional outputs: SSR, relay, logic, current or voltage
Calibration easily adjusted by screwdriver
Upper display indicates process value or value of menu item selected
Lower display indicates set value or menu item selected

Water Resistant Casing The rugged construction is water resistant, making it indispensable in the biological water treatment industry.
One Point Calibration With the probe in saturated air, the meter can be calibrated without the need for chemical solutions.
ATC Circuitry The meter's built-in Automatic Temperature Compensation circuitry will adjust all readings to provide the utmost accuracy.
Low Battery Indicator The low battery indicator gives the user advanced notice to avoid taking an erroneous reading due to low power.

Logging Capability:
Up to 16,000 readings can be stored in the datalogger's memory for retrieval at a later date.
Documented Monitoring:
Ideal for constant monitoring of O₂ levels. It prints date, time, sample #, mg/l O₂ & şC.
RS232 Computer Interface:
The HI 9200 infrared data transmitter (optional) will send the information into a standard PC in seconds
Special Features:
Altitude and salinity factors are automatically compensated for.

ATC Circuitry The meter's ATC feature assures the user of getting accurate temperature-compensated readings.
Low Battery Indicator A built-in low battery indicator prevents a low battery from causing erroneous readings.
Probe Made for Use with BOD₅ bottles The conic shape of the D.O. probe makes it perfect for all BOD₅ applications.
Accurate Thermometer HI 8043 is also an accurate thermometer with an accuracy of ą0.5°C

Battery or VDC power When used for extended periods of time, there is no need to interrupt important tests, simply plug into a 12 VDC battery charger.
Automatic Calibration Simply expose the probe to saturated air and press the CAL button. No need for messy solutions or tedious calibration processes.
Multiple Range You can read in % of saturation or directly in mg/L of dissolved oxygen. The meter can also be used as an accurate thermometer.

Direct dissolved oxygen measurements in ppm or in %
Large and easy-to-read LCD display
Automatic calibration for D.O. and temperature in seconds with automatic value recognition
Automatic compensation for temperature, altitude and salinity variations
Logging of up to 8000 samples divided into 99 lots
PC Communication with RS232C serial interface & Windows^Ž compatible software
