Shanghai Jingqi Programmable Constant Temperature And Humidity Test Chamber BPHS-1000A, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-BP-0042-YJL)

Shanghai Jingqi Programmable Constant Temperature And Humidity Test Chamber BPHS-1000A, model BPHS-1000A is manufactured by Shanghai Jingqi Instrument Co., Ltd.

Studio size: 1000*1000*1000 mm (W×H×D)
Outer box size: 1510*1860*1560MM (W×H×D)
Temperature range: -70°C -150°C can be set
Humidity range: 20% to 98% can be set
Heating rate: normal temperature ----->100°C for about 50 minutes (non-linear no-load, about 3.5°C/min)
Machine accuracy: analytical accuracy (display accuracy): temperature: ±0.01°C; humidity: ±0.1%RH
Control accuracy (test accuracy): temperature: ±0.5°C, humidity: ±1%RH
Distribution accuracy (uniformity): temperature: ±1.0℃, humidity ±2%RH

Control system: Korean programmable TEMI850 temperature controller
The control method can be programmed: System capacity: 100 groups of programs X 120 segments, the number of segments required by each group of programs can be divided arbitrarily, and each group of programs can be freely connected to each other.
Cycle setting: Each group of operation programs can be executed, 9999 times or countless cycles can be repeated, and at this level can be divided into 5 blocks to execute additional part of the cycle.
Operation mode: three operation modes such as fixed value/program/connection can meet the execution of various temperature test conditions.
Control method: intelligent microcomputer PID+SSR/SCR automatic forward and reverse bidirectional synchronous output.
Data setting: Built-in program directory management, which facilitates the establishment, modification, inspection or operation of various test names and program data.
Curve drawing: After the data setting is completed, the setting curve of the relevant data can be obtained immediately, and the drawing screen of the actual operation curve can also be obtained during operation.
Timing control: 2 sets of timing output control interfaces, with 10 kinds of timing control modes, can be used for external logic drive components to execute start/stop timing planning.
Scheduled start: All test conditions can be set to schedule the start-up function.
Operation lock: It can lock the functional conditions of start and stop to prevent other personnel from accidentally touching and affecting the experimental results.
Power failure recovery: with power failure memory device and machine restart mode when power is restored 1. BREAK (break) 2. COLD (cold start) 3. HOT (hot start).
Safety detection: Built-in 15 full-featured system detection and perception devices to ensure the safe operation of the machine. When abnormal faults are sensed, the control power of the machine will be cut off immediately, and the fault occurrence time, abnormal items and troubleshooting measures will be automatically displayed.
Abnormal traceback: It can display the historical data of abnormal faults.
External protection: an electronic over-temperature protection device independent of the controller.
