HM Digital TDS-4 | TDS Meter
The HM Digital - TDS-4 TDS Meter is an ideal pocket-sized meter that can be used for any and all applications, typically for testing TDS and salt levels of freshwater aquariums and ponds. It can also be used for testing water filtration and purification systems, such as RO and DI, to know when to change filters and membranes.
The TDS-4 features a hold function that saves measurements for convenient recording, auto shut-off after 10 mins helps to conserve battery life. Factory calibrated with a 342 ppm NaCl solution.
Note: This meter does not read temperature. For this, you would need to look to the TDS-4TM model or go with an alternative meter such as the TDS 3.
