Page 3: Introduction
INTRODUCTION Environmental Express T80WL Thank you for purchasing Turbidity Meter (hereafter referred to as the instrument). The instrument uses tungsten filament lamp (400 – 600nm) as the light source and 90° scattering method, which is compliant with U.S EPA 180.1 method for the determination of of turbidity in drinking, ground, surface, and saline waters, domestic and industrial wastes. -

· Charge via Power adaptor: connect instrument and power adaptor with a USB cable. Adaptor specification: AC100 to 240V, 50/60Hz, output: 5V/1A. *Note: Please use the power adapter we provide in the kit to charge your turbidimeter. · Charge via Computer: connect instrument and a computer with a USB cable. Under normal circumstances, it is recommended to use the power adapter to charge the lithium battery to ensure the performance. - Page 10 c) Clean vial surface Apply a small drop of silicone oil on the surface of the vial and wipe it off with a lint-free cloth to evenly distribute the silicone oil on the surface in order to cover smudges and scratches, which helps light scattering.

Page 11: Calibration Procedure (Take 0 Ntu And 20 Ntu As An Example)
4.2 Calibration Procedure (Take 0 NTU and 20 NTU as an example) 1) Instrument warm up (only required for low-range or high-accuracy measurement): Power on the instrument, set parameter P2 (continuous measurement time) to 5 times. Long press start continuous measurement (don't insert the vial), then wait for 3 to 5 minutes. 2) Open the flip cover and place the 0.0 NTU calibration vial. -

6) If you want to continue to calibrate 100, 400 and 800 NTU, place the 100 NTU calibration vial in the sample vial holder and press to calibrate. After calibration is done, press to confirm; repeat the steps to calibrate 400 NTU and 800 NTU. After calibration is done, press to return to measurement mode. -

e) The instrument does not automatically recognize the calibration solution. If the wrong solution is selected for calibration, the measurement will be completely wrong. In this case, it can be restored by recalibrating with the correct calibration solutions. Place the instrument on a flat and level surface. Do not hold the instrument in hand while operating. g) If using Formazin standards for calibration, please make sure to use the freshly made Formazin standard to ensure calibration accuracy. -

Diagram 6 5.4 Notes for Measurement Keep the sample stable: After the vial is placed into the sample cell, it is recommended to wait for 1 to 2 minutes before calibration, as the solution will experience some shaking when the vial moves, which may result in inaccurate measurements. -
