Benchtop Environmental Chamber LEC-103

Features

1. 1
   7-inch touchscreen
2. 2
   Wide Temperature Range Provides a temperature range of -20°C to 150°C for testing materials and products under controlled thermal conditions.
3. 3
   Controlled Humidity Environment Supports humidity control from 20% to 98% RH, enabling heat, moisture and damp-heat testing.
4. 4
   Reliable Humidity Control Provides humidity fluctuation of ≤±2.5% RH, humidity deviation of ≤±3.0% RH and humidity uniformity of ≤±3.0% RH at ≥75% RH and ≤±5.0% RH below 75% RH.
5. 5
   PID Temperature Control Uses PID-based closed-loop control with real-time temperature compensation for precise and responsive chamber temperature regulation.
6. 6
   High-Precision PT100 Sensor Equipped with a Class A PT100 armored platinum resistor for temperature measurement and control.
7. 7
   Efficient Single-Stage Refrigeration Uses a single-stage refrigeration system with R404a refrigerant for low-temperature operation down to -20°C.
8. 8
   Controlled Dehumidification The refrigeration evaporator condenses and removes moisture from circulating air, allowing controlled dehumidification within the test chamber.
9. 9
   Uniform Air Circulation A large axial fan circulates air through the chamber using an upper air outlet and lower return-air path for consistent environmental conditions.
10. 10
    7-Inch Touchscreen Controller Features a 7-inch 800 × 480 touchscreen for convenient operation and monitoring of temperature, humidity, running time, lighting and system status.
11. 11
    Programmable Test Operation Provides 50 program groups with 50 segments per program, allowing users to configure complete or partial test cycles, program connections and end or standby actions.
12. 12
    Real-Time Monitoring Displays temperature and humidity set values and real-time process values along with heating output, compressor exhaust and return temperatures.
13. 13
    Data Storage & Export Provides 4 GB storage with historical test data export through USB in Excel format, while test curves can also be saved as BMP images.
14. 14
    Remote Communication Capability Includes RS485 and RJ45 communication ports for computer connection, with optional WAN and mobile-app remote control.
15. 15
    Durable Stainless Steel Chamber The internal chamber is constructed from SUS 304 stainless steel, providing a suitable working environment for repeated environmental testing.
16. 16
    Thermal Insulation Uses 100 mm PU polyurethane foam insulation to support stable chamber conditions and reduce thermal losses.
17. 17
    Adjustable Stainless Steel Shelves Includes two 304 stainless-steel shelves with adjustable height and a load capacity of up to 20 kg.
18. 18
    Anti-Condensation Viewing Window Features a sealed door with four-layer hollow anti-condensation glass and an approximately 240 × 270 mm viewing area for convenient sample observation.
19. 19
    LED Chamber Lighting High-brightness LED lighting provides clear visibility of samples inside the chamber without excessive glare.
20. 20
    Standard Access Port Includes a Ø50 mm test hole with a thermally treated rubber plug for introducing external testing connections while maintaining chamber conditions.
21. 21
    Comprehensive Safety Protection Incorporates compressor over-current, over-pressure and over-temperature protection, along with heater and humidifier over-temperature, overload, short-circuit, leakage, phase-loss, motor overheating and water-shortage protection.
22. 22
    Sample Overheating Protection Provides dedicated sample overheating protection to help safeguard test materials during operation.
23. 23
    Automatic Recovery Functions Includes power-off self-start and power-on self-test functions, along with upper and lower temperature protection and reservation start capability.
24. 24
    Benchtop Construction Designed as a compact benchtop environmental test chamber while incorporating four castors and four foot cups for positioning and installation.
