Utilizes an EPA compliant tungsten light source and state-of-the-art optical system that allows consistently reliable and accurate measurements for turbidity. Users will appreciate the accuracy and sensitivity of this instrument, particularly at very low turbidity levels.

Turbidity is measured up to 1000 NTU. Depending on the measured sample and required accuracy, users can select normal measurement, continuous measurement or signal averaging. Can be equipped with HANNA's optional Tag Identification System (TIS) which allows users to record the time and location of a specific measurement or series of measurements. Logged data (200 records) can be downloaded to a PC through either USB or RS232 connections. Reliable performance of the instrument is validated using Hanna's exclusive Cal Check® system and ready-made, NIST traceable chlorine standards. For turbidity, a two, three or four-point calibration is available using pre-set or user defined standards. Frequent calibration isn't necessary as the system compensates for variations in the intensity of the light source. The instrument's Good Laboratory Practice functions allow traceability of calibration conditions including the time, date and last calibration points. At startup, the meter displays the percentage of remaining battery life. A 'low battery' warning message is also displayed on the LCD to avoid unexpected battery failure. This instrument is equipped with backlighting. The current date and time can be displayed on the LCD. Power: 4 AA batteries or 120 volt AC adapter. Complete with 5 cuvets and caps, calibration cuvets, batteries, A/C adapter and rigid carrying case.
