Constant temperature and humidity maintenance box inspection items and conditions: appearance and data, temperature and humidity, inspection equipment (dry and wet thermometer: graduation value 0.1 ° C).
Calibration method: set the upper limit value of the constant temperature and humidity curing box temperature display to 21 ° C or 23 ° C, the lower limit value is set to 19 ° C or 17 ° C, put into the dry and wet thermometer, test whether the value on the temperature display is The thermometer shows the same. The inspection period is 24 months. During the calibration process, the form is prepared according to the test requirements. All the calibration items are in compliance with the technical requirements.
It is worthy of everyone's attention that the maintenance test of the concrete is different from the structure of the ordinary constant temperature and humidity chamber. The uniformity of the latter is guaranteed by the strong wind circulation (wind speed ≥ 3.7 m / s), while the former if there is strong wind, mixed The condensate will quickly dry and crack, so you must find a professional test equipment manufacturer when ordering such equipment, and use the chamber top micro-hole air supply method to achieve the experimental results.
