HI 9813-0
Waterproof pH/EC/TDS Meter for Growers
HI 9813-0 allows you to measure pH, EC (conductivity) and TDS with just one instrument! This meter has a full-spectrum pH measurement range.
The EC range goes to 4.00 mS/cm. In the TDS range, both instruments use a conversion factor from 0.56 to 0.72 for fertilizer readings, to ensure your measurements fully conform to industry standards.
The specially engineered HI 1285-0 probe is interchangeable and the pH electrode utilizes a fiber junction and gel electrolyte which are particularly suitable when used in fertilizer solutions.
HI 9813-0 and HI 9813-5 measure TDS in the 0 to 1999 ppm range.
HI 9813-5 also performs temperature measurements, with the special probe HI 1285-5.
Order Information:
HI 9813-0 is supplied with pH/EC/TDS probe HI 1285-0, 1 m cable, pH 7 calibration solution (1 x 20 mL), 1.41 mS/cm and 1500 ppm (1 each) calibration solution, cleaning solution (2 pcs), blue protective case, battery and instructions.
