Portable pH/EC/TDS Meter
HI9813-5
Description
The HI9813-5 is an economical, water resistant, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single probe. The meter operation is simplified with dedicated buttons for measurement modes to be displayed on the LCD and knobs for single point calibration of pH and EC/TDS. The HI9813-5 has a variable EC to TDS conversion factor that automatically changes from 0.56 to 0.78 ppm = 1 µS/cm based on the actual EC reading. All readings are automatically temperature compensated using a temperature correction coefficient (β) fixed at 2%/oC. The HI9813-5 is suitable for agricultural, greenhouse and hydroponic applications.
• 3 in 1 probe with pH, EC/TDS and temperature sensors
• Amplified pH electrode for immunity to electrical noise including from ballasts and pumps
• Large LCD with tutorial instructions
The HI9813-5 portable meter features a large LCD which displays either pH, EC, TDS or temperature readings along with tutorial instructions. The pH readings are displayed with a 0.1 resolution and an accuracy of +/-0.1 pH while the EC and TDS readings are displayed with a 0.01 mS/cm and 1 ppm (mg/L) resolution and 2% full-scale accuracy. The EC range of the HI9813-5 is from 0.00 to 4.00 mS/cm and TDS is from 0 to 1999 ppm. The temperature correction coefficient (β) is fixed at 2 %/oC and allows for automatic temperature compensated measurements of EC and TDS. The HI9813-5 is a basic pH/EC/TDS meter that is calibrated manually to a single point with the use of two trimmers. pH is calibrated to pH 7.01 while EC/TDS is calibrated to either 1.41 mS/cm (1413 µS/cm) or 1500 ppm. The LCD screen has battery life indicator as well as on-screen tutorial messages. The supplied HI1285-5 probe is a polypropylene body, amplified pH electrode with a built-in EC/TDS and temperature sensors. The amplifier for the pH electrode prevents interference from humidity and electrical noise from common sources including from motors, ballasts or pumps. The HI9813-5 is a versatile meter for the agricultural, greenhouse and hydroponic uses.
