Digital EC, TDS and Water Temperature Test Pen

Compare supported water readings with a compact pen-style meter. Conductivity, estimated TDS and temperature functions provide references for a suitable maintenance or checking routine.

• ✅ View a conductivity reading - EC gives a measure of electrical conduction in the sample.
• ✅ Use a TDS estimate - the supported mode converts the conductivity response into a displayed reference.
• ✅ Read temperature too - Celsius and Fahrenheit display options are listed.
• ✅ Keep the instrument portable - the pen format is convenient for suitable samples.

Know What the Reading Does and Does Not Show

Calibrate and use the pen according to the actual instructions, with suitable reference solutions where required. Keep the sensing area clean and compare readings under consistent conditions.

The fourth advertised function is temperature in another unit, not an independently established hardness test. EC/TDS does not identify contaminants or prove water is safe to drink. It is not a substitute for appropriate water analysis.
