product description
General information:
The HD25.2 is a digital turbidity meter for laboratory and mobile use, suitable for measurements in drinking water, waste water and process liquids. The working principle is based on the nephelometric (90° scattered light sensor) method.
It is equipped with three light detectors and two LED light sources (white and infrared) which are permanently kept under control in order to guarantee long-term stability. The instrument performs measurements according to the standards EPA 180.1, ISO-NEPH (ISO 7027), EBC and ASBC. It is also able to carry out measures of transmission factor percentage of white and infrared light.
The initial factory calibration is based on Formazin primary standard. For routine calibration a set of stabilized secondary standard solutions is available: STCAL (turbidity standards for calibration):
- STCAL 1 less than 0,05 NTU
- STCAL 2 equal to 8 NTU
- STCAL 3 equal to 80 NTU
- STCAL 4 equal to 800 NTU
User calibration is automatic on one or four points, depending on the measuring variable. Stabilized power supply and advanced electronics guarantee optimal performances over time. The HD25.2 is a datalogger that stores up to 999 samples. The data can be transferred from the instrument connected to a PC via the RS232C and USB 2.0 serial ports. The RS232C serial port can be used to transfer the acquired measurements to a 24 column printer (i.e. HD40.1).
The print function allows to print labels with progressive and automatically incrementing numeration, with all data related to the sample being examined. The dedicated software DeltaLog11 allows instrument management and data processing on PC.
The use of the HD25.2 by more users is facilitated by the “User Management” function, which allows, according to the case, to enable or disable some advanced functions of the instrument through password. The protection degree is IP66.
