KHR-A Heat treatment Quenching Medium Cooling Performance of Portable detector quenchometer


The detector is used to test the effect and quality of quenching liquid and oil in heat treatment industry. Sometimes, when we are not ensure the quality and effect about the quenching oil and liquid we purchased from supplier; or the efficiency of the quenching water (PAG) or oil may recede. In cases, the detector may help us to foresee the adverse situation, and avoiding loss happens in quenching process.


How to use


  • The detector comply with the standard of ISO9950:1995
  • It uses thermocouple and nickel alloy probe to test the quenching liquid and oil
  • The testing result can be judged via the cooling curve
  • After heating the probe to 850 centigrade degree (normally), insert probe into the quenching liquid or oil, the machine may record the deference of the data as the temperature of probe and time changes. Finally, the printer on the machine may provide the data and curve, and it may help us to research the data.


  • Smaller size and easy to move
  • Working Stably and accurately
  • It may upload the data to computer
  • Directly test the material of the quenching liquid or oil, in comparison with traditional testing, the result is more accurate.

Product function

  •  Adopts specially made probe for HSS quenching, Stainless steel solid melting ect performance test of cooling medium;
  • Heating process and cooling process of testing, such as induction hardening, large castings and forgings heat treatment process detection etc;
  • Determination of water-based quenching medium in different stir intensity (Tensi method cooling standard device) under the cooling performance.

Cooling curve method: Maximum cold speed Vmax; Maximum speed Tvmax; the temperature of cold 300 °C when cold speed v300; Cold to 600 °C, 400 °C and 200 °C time t400 and t200 t600.

KHR be widely applied in check room standard again under the condition of different quenching medium performance comparison testing,suitable for the field work environment of cooling bath control, it is to improve Heat treatment product quality, reduce and eliminate waste effective means.
1, On-site measurement of the cooling characteristics of a quenchant , directly in the quench tank, so as to:
1) Test the cooling performance at various positions in the quench tank;
2) Follow changes in the cooling performance of a quenchant-as a result, for example, of degradation or impurity –over a period of time
2, Laboratory measurement
3, Tests of different quenchant e.g. oils, polymers, water and salt
4,  Incoming inspection of quenchants
For heat treatment plant
♥  Experimental determination of the production parts with a certain kind of liquid cooling groove maximum cold speed minimum and maximum of 300 °C cold speed, as bath monitoring criteria;
♥  Cooling bath site regularly detection;
♥  Detection cooling bath different parts and stir intensity under different cooling characteristics and to optimize the cooling process and equipment;
♥ Quenching quality accident (quenching cracks, deformation, not quench) analysis;
♥  Cooling medium restocked acceptance.
For cooling medium production unit
♥  Analysis medium composition and characteristics of the relationship, determine the cooling medium composition, Develop new products;
♥  Product quality monitoring
