Features
1. corrosion test chamber has an automatic/manual water adding system, which can automatically replenish the water level when the water level is insufficient, and the test is not interrupted.
2. The temperature controller uses digital display, and the PID control error is ±01.℃;
3. salt corrosion chamber,Double over-temperature protection, warning of insufficient water level to ensure safe use.
4. The laboratory adopts the direct heating method of steam, the heating speed is fast and uniform, and the standby time is reduced.
5. Salt Fog chamber,The precision glass nozzle is sprayed with adjustable mist, and the conical disperser of the spray tower of the mist volume is evenly scattered and diffused, and naturally falls on the test card, and ensures that no crystalline salt is blocked.
The ASTM B117 cycles include
Step 1: 35°C salt spray
Step 2: Go back to Step 1
Conditions for the salt spray test chamber to be used for ASTM B117 testing:
Salt spray deposition rate measured with a 100mm diameter funnel: 1–2 ml/hour;
Recommended spray pressure: 8psi;
Recommended solution flow: 1100 liters, 0.6 liters/hour; 600 liters, 0.5 liters/hour
