The most essential testing equipment for shrimp keeping.
TDS pen will check the solvents that is dissolved into the water that is not water. Too much TDS your shrimp will have molting issues, too little TDS your shrimps will molt and cannot form a proper shell back. TDS does correlate to gH but not pH. Different remineralization products will have different gH and TDS. It is essential to know your range and keep it stable.
Economy model that is ideal for end-users.
Highly efficient and accurate due to its advanced microprocessor technology.
Hold Function: saves measurements for convenient reading and recording.
Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking ‘x10’ image.
Display: large and easy-to-read LCD screen.
Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
Fun, translucent blue housing that’s very strong and durable.
Includes a TDS chart sticker on the back of the meter that explains TDS values.
