● DWH-P-T series walk-in constant temperature and humidity laboratory adopts high-precision 7-inch touch screen PLC controller (with 1~N level authority management, authority can be freely assigned, with audit trail function), suitable for scientific research institutions, High-end colleges and universities, pharmaceutical industry, electronic military industry, food and other industries.

● Controller: high-precision 7-inch touch screen controller (independent research and development, with 1~N level authority management, with audit trail, alarm record function), low failure rate, precise control, simple and clear human-computer interface

● Compressor: Original imported fully hermetic compressor (top-notch), high efficiency, low noise, long life, to ensure long-term stable operation of the equipment

● Humidity sensor: original imported humidity sensor (top-notch), high precision, low annual drift rate, long life without maintenance

● Temperature sensor: Original imported temperature sensor (Class A), with high accuracy, low annual drift rate, long life without maintenance, and avoid the overall high cost of replacement caused by the use of a temperature and humidity integrated sensor

● Insulation layer: high-density flame-retardant polyurethane foam is used, which has good thermal insulation and moisturizing performance and high fire resistance

● Inner liner: 304 mirror stainless steel, polished with four corners arc, easy to clean, the bottom is inclined to avoid problems such as sample damage caused by accumulated water

● Box body: The national standard 1.2mm thickened cold-rolled sheet is used, which can withstand long-term impact under high temperature and high humidity conditions

● Data integrity: online printing (miniature needle-type printer, direct long-term archive, no need to copy), recording (exported from U disk, storage capacity of more than 5 years), curve viewing, alarm recording, operation in compliance with relevant regulations and standards record, etc.

● Protection device: with compressor overheating protection, overpressure overload protection, water shortage protection, double overtemperature protection, humidification tube air-burning protection, etc.

● Alarm system: buzzer alarm (long transmission distance), sound and light and remote SMS/telephone alarm (optional)

● Regulatory compliance: Chinese Pharmacopoeia 2020, FDA, EU-GMP, c-GMP, ICH-Q1A(R), GB/T10586-2006
