HANNA HI-9813-51 pH/EC/TDS - Combination Meter
HANNA HI-9813-51 pH/EC/TDS - Combination Meter
Product code: HP00052044
Product Description
The HI 9813-51 Combination Meter is a versatile, water resistant multiparameter portable meter specifically designed for agriculture, hydroponics, greenhouses, and nurseries. It features an extra large LCD that clearly displays the parameter being measured as well as calibration instructions.
This meter features a large LCD which displays either pH, EC (Electrical Conductivity), TDS (Total Dissolved Solids) 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 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 EC 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 battery 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 features 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 HI-1285-5 electrode is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. The EC/TDS portion of this probe utilises two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples.
- Multi-functional - can measure multiple parameters at the same time.
Storing your electrodes correctly is a vital part of maintenance, preventing contamination and ensuring accurate measurements when testing pH.
Why not use water?
Deionised or distilled water shortens the lifespan of your electrodes. Plain water causes the salt contained in the reference cell to diffuse out - leading to slower response times when testing.
Storage solution is specifically formulated to maintain the concentration of salt required for the reference cell, while preventing your electrode from drying out.
Use storage solution consistently for electrode longevity.
