Calibrators: Series 2853N & 3850N
Our Calibrators are designed to cover electronic process
control instruments in the following range of I/O parameters.
| Input Parameter |
Range |
| DC Voltage |
10 Millivolts ~ 25 Volts |
| DC Current |
0 ~ 55 mA |
| Resistance |
100 ~ 2500 Ω |
We offer the following 2 groups of Calibrators both covering
the above range.

Our Series 2853N Calibrators are multi-parameter precision
instruments which are suitable for plants having many types
of Instruments. Our equally precise Series 3850N Calibrators
are single / dual parameter instruments which replace our
earlier Series 2851N & 2852N calibrators. They offer cost-effective
solutions for plants having fewer types of instruments. They
are also suitable for plants having innumerable instruments
of the same type. In fact they are designed to speed-up mass
calibration jobs in manufacturing and shut-downs at low cost. Our current product
range includes the following models.
