Summary

  The instrument is designed as a professional low temperature thermostatic water bath matched with low temperature penetrometer according to the China Transportation Industry Standard JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering,especially  the regulations of T0604-2011 Bitumen Penetrometer Test.At low temperature condition,it is mainly suitable to ensure the low temperature,constant temperature and heat preservation of the test water bath when doing the bitumen penetrometer test.The instrument also can be used in other constant temperature and heat preservation of the opened circulating system.

I. Main technical features

1.The closed water container can circulate the constant temperature and heat preservation of the opened penetrometer
   test water bath.

2.Test temperature range (5.0~100.0)℃ can set at random,it can create the presetting,constant low temperature
   environment according to the requirement of test sample.

3.The instrument can be used in constant temperature and heat preservation of other opened circulating system.

4.Floor structure,conveniently using and moving.
