Tester measures pH, conductivity, TDS, and temperature.

Press Release Summary:

Waterproof, digital tester models HI98129 and HI98130 are designed for pH, EC/TDS, and temperature measurement with respective accuracies of ±0.05, ±2% FS, and ±1°F. Featuring automatic temperature compensation, units offer selectable EC/TDS conversion factor and temperature compensation coefficient. Elements of construction include dual-level LCD and replaceable pH electrode cartridge with cloth removable junction and EC/TDS graphite electrode.

Original Press Release:

Single Waterproof Digital Tester That Measures pH, Conductivity, TDS And Temperature

Kernco Instruments Co., Inc., is pleased to introduce its Catalog No. HI98129 and HI98130 combination digital tester that will measure pH, conductivity, TDS and temperature designed for use by fruit and vegetable growers as well as other growers. Also ideal for use in water treatment, cooling towers, printing industries, plating shops, etc.

Major features and other information:
The NEW HI98129 and HI98130 Combo waterproof testers are designed for high accuracy pH, EC/TDS and temperature measurements. No more switching between meters, the Combo does it all. All pH and EC/TDS readings are automatically temperature compensated (ATC) for. The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient ß. The Combo is waterproof, floating and has a large easy-to-read dual-level LCD and Automatic shut off. The Combo has a replaceable pH electrode cartridge with a cloth removable junction as well as an EC/TDS graphite electrode which resists contamination by salts and other substances that come in contact with the electrode. Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester meets the requirements of multi-routine measurements.

Additional key features:
o Battery Life Percentage Illuminated
o pH stability and ATC Indicators
o User Adjustable TDS Ratio
o Adjustable Temperature Coefficient Factor
o Calibrate to Standard of NIST Buffers
