Details
Engineered especially for applications involving demineralized and deionized water, the HI983304 is a simple way to measure very low conductivity. You can simply hang the meter right above the output of any demineralization system to be tested for continuous measurement and the unit will run without interruption on 12 VDC power supply or take it with you for spot checks. The built-in visual alarm will activate when any measured value differs from the set point by 1.00 µS/cm, meaning that the demineralizing equipment has been exhausted. This exclusive feature will ensure maximum system efficiency with minimum investment.
The meter housing is rated IP54 meaning it has a high level of protection against particles and a fair amount of protection against water splashing from any direction. The integrated large LCD allows for an easy reading from a distance and can measure with great accuracy up to 19.00 µS/cm.
The meters are supplied with a HI7631 probe that automatically compensates for any temperature variation. The HI7631 is a two-pole amperometric EC probe with a built-in temperature sensor for Automatic Temperature Compensation (ATC) and has a ½” male NPT threaded connection for insertion mounting. The polyethylenimine (PEI) protective sleeve resists most aggressive chemicals.The HI7631 probe provides a rapid response and high accuracy EC measurement. When using the HI983304 in pure water applications, there is no need to clean or calibrate the EC probe.
