Calibration Bath India and Calibration Bath Manufacturers


Weiber Calibration temperature baths provide optimal temperature environments for “secondary” or “comparison” temperature calibrations. They offer unsurpassed stability and uniformity, a large working volume, and flexibility for performing thermometer calibration on calibrating a variety of temperature sensors. It not only allows calibration of multiple systems at the same time, but also offer the added advantage of accommodating sensors of all shapes and sizes.These high temperature baths provide calibration temperature upto300°C.

Calibration baths are stable to ±0.001 °C and do not require calibration blocks or use of special calibration techniques to achieve that stability. Standard as well as customized models are available.

  • Large-capacity tanks for higher productivity
  • Calibrations up to 300 °C
  • Built-in cooling coils for faster cooling
  • The units are operated via an innovative and user friendly control panel which includes an LCD display, and offer configurable PID controller (HMI+PLC as an option)
  • Visual and audible alarms in the event of a failure
  • Dual protection system against uncontrolled over-temperature events:
    • Heating elements turn off automatically if measured temperature exceeds the set threshold by 5°C
    • Mechanical over-temperature device shuts off heating elements if temperature exceeds maximum allowed values
  • Variety of liquids that can be used

  • The outer construction of calibration bath is epoxy painted PCRC sheet/SS 304(as per requirement).
  • The inner chamber is constructed out of high grade SS-304.
  • The temperature is controlled by nanotechnology based ergonomic controller
  • Callibration Bath Manufacturers

  • Temperature range: -30 to 300OC. however we can modify the same as per requirement.
  • Cooling unit: the cooling unit comprises of CFC free compressors of Kirloskar/Tecumseh / Bitzer/ Danfoss make, conforming to latest international standards and guidelines.




Air-cooled condenser is internally grooved finned copper tubes used for high heat transfer area, which not only reduce power consumption, but also bring down the condensation faster. This unit is designed. & verdigris & reduces the resistance, saves energy consumption and ensure good heat exchange.


Single stage Reciprocating Compressor. Give the High Efficiency compared to sealed compressors, Less Power Consumption , Accessible for repairing, low noise level, Less Vibrations, Wide Voltage Range, Designed for Extremely High Ambient ,Full warranty etc.


The compressor is mounted perfectly to ensure recommended level of sound and vibration.

(B.) REFRIGERATION CONTROL (a).Low and High Pressure switch of RANCO/Danfoss

Which ensures the compressor and refrigeration system when low pressure will occurs it trip off the compressor. This is the only operator friendly switch can easily reset.

(b).Hand Shut off Valve

Is the only Condensing Unit, which is equipped with it. This valve is used for pump down the total gas in to the condenser & receiver in the faulty condition.

(c).Liquid Dryer of Danfoss make

Which is equipped in the liquid line for ministration of moisture in the liquid. It will collect all the moisture in side the refrigeration line as well as gas.

(d).Moisture Indicator of Danfoss make

The sight glass area in the Moisture Indicator shows at a glance the condition of the refrigerant system. The moisture indicator element changes colour and indicate if the system is safely dry, or dangerously wet.

(e). Solenoid Valve of Castle make

In most refrigeration applications, in order to automatically control the flow of fluids in a system, it is necessary to be able to start or stop the flow in the refrigerant circuit. An electrically operated solenoid valve is usually used for this purpose. Its basic function is the same as a manually operated shutoff valve, but it can be positioned in remote locations, and may be conveniently controlled by simple electrical switches.

(f). Oil Separator of Stainless Steel 304

The oil separator intercepts the oil mixed with compressed gas and returns it into the crankcase of the compressor, thus assuring an efficient lubrication of its moving parts. Also, it improves the overall efficiency in the system.

(g). Suction Accumulator

Maximum Efficiency of the relief device (expansion valve) because it is supplied with sub cooled Liquid.

(h). Liquid Receiver

As per ASME Section VIII Division I for storage of refrigerant.
