Suited to horticultural and hydroponics applications, and especially for testing water-based nutrient and chemical solutions, it simultaneously displays nutrient concentration with either pH or temperature. Two LCD displays indicate pH over the range of 0-14 and temperature from 0-49.9 degsC.
The unit, priced £99 + VAT and carriage, is housed in a tough, water-resistant case. It incorporates automatic temperature compensation, one-touch auto-calibration and a user-selectable backlight. Four AA batteries (supplied) power the device and auto power-off maximises battery life.
