Product Details

HI9812-51 Portable pH/EC/TDS/Temperature Tester

HI9812-51It is a portable waterproof instrument designed to pair with the HI1285-51PH/EC/TDS/Temperature multi parameter probe. The instrument is easy to use, with dedicated keys for clear display of measurement modes on the LCD, as well as knobs for pH and EC single point calibration. The tutorial message on the screen guides users to complete calibration and measurement.

1. 3-in-1 probe with pH, EC/TDS, and temperature sensors

2. Suitable for hydroponics, greenhouse, agriculture, and groundwater applications

3. Large LCD display screen

The HI9812-51 portable pH/EC/TDS/temperature analyzer is a pH/EC/TDS instrument used for agricultural, greenhouse, and hydroponic applications.

These instruments are equipped with a large LCD that displays pH, EC, TDS, or temperature readings as well as tutorial instructions. PH readings are displayed with a resolution of 0.1 and an accuracy of+/-0.1 pH, while EC and TDS readings are displayed with a resolution of 10mS/cm and 10ppm (mg/L) and a 2% full-scale accuracy. The temperature correction coefficient (β) is fixed at 2%/° C, allowing for automatic temperature compensation measurements of EC and TDS. These instruments are manually calibrated to a point using two adjusters. The pH value is calibrated to pH 7.01, while EC/TDS is calibrated to 1.41mS/cm (1413 µ S/cm) or 1500ppm. There is a battery life indicator and tutorial information on the LCD screen.

When switching measurement parameters between pH, conductivity, and TDS, there is no need to change the probe. These multi parameter instruments reduce the number of instruments required for daily water quality analysis.

All models provide probes with a polypropylene body, an enlarged pH electrode with built-in EC/TDS and temperature sensors. PH electrode amplifiers can prevent interference from humidity and electrical noise from common sources, including motors, ballasts, or pumps.
