Environmental working conditions must be met.2. The measuring cell must be clean and dry for a long time. When not in use, dust shall not be covered on the shield.3. In humid climate, the start-up time must be extended.4. The test solution should be poured carefully along the sample bottle to prevent bubbles from affecting the measurement accuracy.5. Replace the sample bottle or recalibrate it after repair.6. Non-professional maintenance engineers should not open the instrument for maintenance.

• 【WORKING PRINCIPLE】The portable turbidity meter adopts a high-precision optical system. The measurement principle is based on the 90 scattered light of the infrared light source under the turbidity measurement, and zero calibration can be performed at the same time.
• 【FUNCTION】Data nonlinear processing and data smoothing function,quick and automatic multi-points calibration self-diagnostic information prompt, select-able span – automatic or manual switch.
• 【EASY READING】The laboratory turbidity meter can meet the needs of various scenarios, allowing you to easily read data at night. It adopts a backlit LED display design and clear readings.
• 【LIGHTWEIGHT AND PORTABLE】The digital turbidity meter is exquisite in workmanship, lightweight, easy to carry, and can automatically shut down. Precise light route system, reliable positioning structure, effective tone compensation, direct turbidity reading.
• 【WIDELY APPLICATION】The portable turbidity meter widely used in water works, water treatment plants, swimming pools, food and beverage industries, is an essential instrument for water laboratory.
