According to the EN and ASTM standards, Matest calorimeters allow to determine the heat of hydration thanks to the use of isolated containers and specific equipment capable of measuring the temperature increase in the mixture due to the chemical process of hydration.
Used to measure the heat of hydration of cements by means of semi-adiabatic method.
The equipment consists of:
- Testing calorimeter, calibrated, dia. 160 by 350 mm
- Reference calorimeter (same of the testing one), without certificate.
- 50 mortar box and 20 sand bags.
- Measuring system complete with two temperature probes, modem, software to record temperature, analyze and display data with wireless transmission to modem.
Used to determine the heat of hydration of low heat Portland and hydraulic cement.
The apparatus consists of a Dewar flask contained in an insulated material and housed in a wooden box which is hinged so that the flask can be easily removed or replaced.
A second hinged wooden box contains the first one, granting a better insulation, as expressly requested by the a.m. Standards.
The Calorimeter is supplied complete with a constant speed electric stirrer, and filler glass funnel.
The standard supply does not include: the thermometer (to be selected from digital models; see accessories) and the propeller (selecting it from the specific Standard; see accessories) which must be ordered separately.
Power supply: 230V 1ph 50Hz 150W
Dimensions: 350x250x680 mm
