Floating-type thermometers feature a protective casing and a secure rope design, providing precise measurements, easy readability, durability, and allowing you to monitor water temperature at any time.

Carefully selected optical hydrometer with a lightweight and compact design, including a storage box, for precise measurement of the specific gravity of saline solutions.

Handheld design with an anti-slip pen-type handle, equipped with built-in Automatic Temperature Compensation (ATC) for accurate results. Large LCD display with switchable backlight and automatic power-off after 5 minutes of inactivity.

Power source: 1.5V LR44 button batteries x 4 or 1.5V AAA batteries x 2 (batteries not included).

The ultra-thin electrode glass provides exceptional accuracy, allowing for precise monitoring of pH levels and crucial measurement of water quality in aquaculture.

Battery: 4 × 1.5V (AG13 button batteries).

Measures the TDS (Total Dissolved Solids) of various conductive substances in water, including calcium, magnesium, iron, aluminum, arsenic, lead, potassium, phosphorus, and others. The displayed value represents the total impurity content per liter, e.g., a reading of 100 indicates 100 mg of impurities per liter. The instrument locks the reading for easy reading and recording, and it automatically shuts off after ten minutes of inactivity.

TDS Value:

Springwater: 100-200 ppm

Tap water: 100-250 ppm
