อุปกรณ์วัด Multiparameter (Portable pH/EC/TDS/Temperature Meter with CAL CHECK™ Feature)

HI 9813-6

Portable pH/EC/TDS/Temperature Meter with CAL CHECK™ Feature

HI 9813-6 is a versatile, water resistant, multiparameter portable instrument specifically designed for agricultural applications such as hydroponics, greenhouses, farming and nurseries.

This meter features an large LCD that clearly displays the parameter being measured as well as calibration instructions. Calibration is fast and easy with knobs located on the front panel of the instrument.

HI 9813-6 includes all the features of the HI 9813-5 while incorporating our exclusive CAL CHECK™ feature. CAL CHECK™ allows the user to easily check the pH probe calibration status at any time.

This instrument utilizes the HI 1285 series pH/EC/TDS/temperature probe. This probe features a fiber junction and gel electrolyte making it ideal for fertilizer solutions.
