How to use

Immerse the sensor end of the tester into the water sample according to the device’s markings, ensuring the probe is sufficiently covered. Power on the unit and wait for the LED display to stabilise; the tester will show measured values for each parameter sequentially or via dedicated indicators. Remove the probe after reading, power off the device, and dry the sensor before storage. For repeat measurements, rinse the probe with clean water to avoid cross-contamination between samples.

Usage recommendations

Use the Bigstern 4-in-1 tester for routine spot checks rather than as a substitute for laboratory analysis. Calibrate or validate measurement accuracy according to the manufacturer’s instructions when precise results are required. Store the tester in a dry place, avoid prolonged exposure to direct sunlight, and replace batteries when display dimming or inconsistent readings occur.
