Pressure resistance: water pressure 20MPa Weight: 2.5 kg Overall dimension: 650 * 450 * 500 mm Temperature range: 0 ~ 40 ℃ Response time: < 4 S Resolution: 0.0001 ℃ Linearity: < 0.08% per 5 ℃ temperature rise range Temperature measurement error: ± 0.003 ℃ for every 5 ℃ temperature rise range Power supply voltage: AC220V ±... - Page 6 water overflows at the overflow port. Rear view of instrument Power Power supply base Water outlet Spillway 2.Instructions for use of the instrument The main interface of the instrument is as follows Figure 1 (1)：system [system]: click "system setting" to enter the system setting menu, as shown in the figure below...
- Page 7 Figure 2 [heat capacity]: click the display box behind the heat capacity to pop up the keyboard and input the heat capacity The heat capacity of the system is positively proportional to the measured calorific value. Input the average value of the calibrated heat capacity, click return, save and return to the main interface of the system.
- Page 8 [ignition heat]: click the display box behind the ignition heat to pop up the keyboard and input the ignition heat. The heat generated by ignition is set at 150j when leaving the factory. If the length of ignition wire and cotton thread is not changed, it is generally not necessary to change. To change, enter a new value, click return, save and return to the upper menu [additive value]: click the display box behind the additive value to pop up the keyboard and input the additive value.

- Page 10 Click stop test to finish all functional tests. (2). [calorific value determination] Click the calorific value measurement button, the calorific value test starts, and the interface switches to the following: Click calorific value input as follows: Input the weight of the sample (if no additives are used, you can input 0), serial number, hydrogen sulfide, water and other experimental data, and click back to return to the calorific value measurement interface.
- Page 11 Click the calibration input as follows: Input the sample weight, number and other test data, and click return to return to the heat capacity measurement interface. (4). [return] When the test is over and ignition fails, press this key to clear the test information and curve and return to the standby state.

benzoic acids is calculated and compared with the standard calorific value, and the error is less than 120J, which means that the calibration is successful. (7) Calorific value measurement Weigh the sample (0.9 ~ 1.1g), load the oxygen bomb, charge oxygen for 15 ~ 45 seconds, pressure is 2.8 ~ 3.2Mpa, put it into the inner cylinder, click "calorific value test", the instrument will start calorific value measurement, input the weight of weighed sample, input the weight of additive, if there is no additive, you can input 0. - Page 13 VIII.Packing list Item Main engine Power cord Oxygen bomb Oxygen flushing instrument Pressure gauge Ignition wire Cotton Benzoic acid Add drain pipe Tweezers Printing paper Oxygen bomb support crucible Oxygen bomb sealing ring Small scissors 1mLSample injector 5mLSample injector 10mLSample injector...
