This 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 1ppm (mg/L) resolution and 2% full scale accuracy.

The EC range of both meters is from 0.00 to 4.00 mS/cm and TDS is from 0 to 1999ppm.

The temperature correction coefficient (β) is fixed at 2%/°C and allows for automatic temperature compensated measurements of E and TDS.

This meter 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 1.41mS/cm or 1500ppm. The LCD screen has batter life indicator as well as on-screen tutorial messages. No probe changes are required when switching your measured parameter between pH, conductivity and TDS.

This multiparameter meter reduces the number of instruments required for daily water quality analysis. The supplied probe feature 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.

About the HI-1285 series probes

The HI-9813-51 and HI-9813-61 are supplied with a polypropylene body pH/EC/TDS/temperature probe. The pH, EC, TDS and temperature sensor are housed in a single body that connects to the meter with a DIN connector.

Features

3 sensors in a single probe

Amplified pH electrode – The pH electrode has a built-in amplifier that will reduce the effects of electrical noise on the high impedance pH measurement. Examples of sources of electrical noise include motors, ballasts, and pumps which are common in greenhouses.

Amperometric EC/TDS sensor – The EC/TDS readings are performed by an amperometric sensor. An alternating voltage is applied to the sensor and the amount of current that passes between the two stainless steel pins is dependent upon the amount of salts (fertiliser) present. A greater amount of salt present results in an increase in conductance.

Polypropylene body - The body houses all the sensors in a single body design and is durable. The probe is gel filled for maintenance-free operation. It does not have to be refilled.
