Clarity of water is extremely important in products destined for human consumption. Suspension free water is also considered necessary for industries manufacturing beverage, food products etc. Similarly, minimum limits of turbidity are required to be observed in drinking water & sewage disposals. SANSEL Digital Nephelometer Model DN 1000 are ideal instruments for measurement of suspensions. They consist of a light source focused on a test tube containing the sample solution under test. The light, reflected at right angle to the focused light by the suspension in the solution, is detected by the photo electric detector, amplified and displayed on a 3½ digit LED display.

SANSEL offers PI 542A Model PROCESS INDICATORs are extremely versatile
Indicators that can be used for a wide variety of applications. These INSTRUMENT
offer extreme reliability and low cost for Process measurement and logging. PI 542A
is a Microprocessor based instrumentation ensures accurate readings for all Linear
Parameters. A number of programmable features including In-line calibration are
standard. All the parameters are saved in a non volatile EEPROM memory which
doesn’t needs any external battery.
PI 542A can offer relay outputs for signals exceeding set points. Programmable
Re Transmission output models are also available in addition to the industry
standard 4 -20mA or 0 – 10V DC output. Optional RS 485 (2 wire ) output also
provided for PC communication with PC Interface software & also with MODBUS RTU
protocol.

SANSEL Model HCAL 1104U Humidity and Temperature Generator is to perform a rapid & easy calibration of portable instruments, sensors, Transmitter and data logger of different manufacturers. Solid state Heating & Cooling technology with high performance humidification system, generate precision chamber stability & uniformity gradient range from 5 to 60°C / 5 to 95 % RH*.

Exact Pressure Measurement and Monitoring are Must in Applications Crucial to Operational Safety of
Machinery and Industrial Installations.
Regular Inspection of the Pressure gauges / sensor / transmitters / indicators Used in these Applications is
Absolutely Essential for Economic and Technical – Safety Reasons and is Already Prescribed as Obligatory in Many
Sectors.
