YH-40B-type standard concrete curing box of a standard concrete curing box overview (Hebei Xing day test equipment factory) in this series YH-40B-type standard concrete curing box with advanced intelligent temperature and humidity control system, can accurately instruction warming, cooling and humidification functions. Fully automatic switch work to achieve dynamic equilibrium inside temperature, humidity, and placed the printer and the water level sensor automatically timed. Thereby enhancing the accuracy and automation control temperature and humidity levels prescribed standard curing conditions, reduce energy consumption, to replace the existing low level of standard curing box and corporate self-built non-standard curing room, realize specimen conditioning and testing of the standard environment . Two, YH-40B-type standard concrete curing box main technical parameters Temperature accuracy ± 1 ℃ Temperature measurement accuracy ± 0.5 ℃ chamber temperature is 20 ℃ heating power 500W temperature difference <± 1 ℃ machine noise <65dB Operating voltage 220V ± 10% control Precision of ± 1% RH relative humidity measuring precision ≥92RH ± 3% RH Frequency 50HZ 136W compressor power stage temperature and humidity sensor Pt100A volume: 20B-type 600 * 500 * 960mm (cement test block 20 groups) 40B type 600 * 500 * 1180mm (cement test block 40 group) 60B type 580 * 1200 * 1400mm (concrete brick Group 18) Third, YH-40B-type standard concrete curing box The instrument works with precision Pt100 platinum resistance temperature sensing element, the high-performance ( A / D) converter will be transferred to the multiplexer. Temperature and humidity equivalent voltage signal into a corresponding digital signal, and then post-processed by the display and control chip microprocessor. When the temperature is below the set temperature control value limit, the meter output heating control signal, when the temperature is higher than the set temperature control value limit, the meter output cooling control signal, when the temperature is the setting control values ??window area (CER setting area), the meter stop heating or cooling, into the constant temperature. When the humidity control humidity is below the set limit value, the instrument signal output humidification, humidity control values ??when humidity is higher than the lower limit set by the humidification stop. Four, YH-40B-type standard concrete curing box for use 1, the instrument should be placed in dry air at ambient temperature 2 ~ 38 ℃, relative humidity less than 85%, around without a strong vibration and strong electromagnetic fields affect indoor use. 2, the instrument placed smoothly, should check the door switch is flexible, electrical, refrigeration and other components for damage. 3, the water inside the tank to the end of the shelf layer below the heating pipes more than 2cm, the side door opened to fill the humidifier tank filled with distilled water, another the temperature in the wet box plastic ball filled with water, and put gauze soak into the water. 4, the power plug into 220V outlet with a good grounding in, press the power switch, the instrument automatically enter the working state. 5, the factory of the instrument has been incorporated into the standard-setting process, the temperature control is 20.0 ℃ ± 1.0 ℃, humidity control value of 95% ± 1.5%, no special requirements, you can not change the control program, otherwise it will likely temperature control, control humidity are outside the scope, such as the need to change the control value of the data, you can modify the program according to the temperature controller manual. Five, YH-40B-type standard concrete curing box instrument operating parameters (factory standard procedures setting) 1, temperature control value 20.0 ℃ 2, temperature control limit (to control the value of the reference) + 1 ℃ 3, humidity control of 95% 4, Temperature control limit (to control the value of the reference) -0.5 ℃ 5, humidity control limit (to control the value of the reference) 1% 6, humidity control limit (to control the value of the reference) 1% six, YH-40B-type standard concrete curing box test detects refrigerator humidifier can work, can artificially to dry temperature sensor head heated to above the set temperature 10 ~ 15 ℃, so make the difference between wet and dry temperature increase, chillers, humidifiers begins jobs. Seven, YH-40B-type standard concrete curing box Note 1, the power supply voltage fluctuation exceeds a predetermined range, you must install a power stabilizer, otherwise it will damage the instrument and refrigerator. 2, the power must be reliable grounding, poor ground will your personal safety at risk. 3, always check the humidifier, water, wet box do not water, to replace the box of gauze month. 4, non-related persons can not arbitrarily change the control program data, so as to avoid damage to the instrument and the instrument out of control. Eight, YH-40B-type standard concrete curing box general troubleshooting 1, the machine does not work: Check the power switch, the fuse is damaged. 2, not cooling: Check the cooling state meter is displayed, check the compressor overload protection, the starter is damaged, the compressor can work without cooling it may be a refrigerant leak. 3, no humidifier humidifier: small fan inside the humidifier checks whether the work, the humidifier base water level is too high, place the humidifier is tilted too much, atomizer transducer is clean. 4, the temperature difference between inside: Check the fan is working, the cooling indicator light and the fan does not work, then the fan is damaged or bad fuse. 5, occasionally affected by external electrical shocks, digital instrumentation appear out of control, simply turn off the power switch or disconnect the power plug, and then reboot, that is able to work properly. Nine, packing list host 1, a shelf, a fuse, gauze 1, Manual 1, Certificate 1.
