Page 14: Handling Precautions
Handling Precautions Meter and sensor The sensor is a consumable part. If it becomes damaged or its performance deteriorates, replace it with a new one (the sensor can not be repaired). Do not swing the meter and sensor by holding a strap. To ensure the waterproof performance, confirm the followings when attaching the sensor. - Page 15 Do not measure samples such as the following, since they may damage the sensor or shorten its life: Organic solvents, oils, adhesives, cement, alcohols, concentrated acid (0 pH to 2 pH), concentrated alkaline (12 pH to 14 pH) or solid materials. In the following cases, perform electrode surface treatment as instructed on page 8.
