This sensor is intended for professional applications or removable interlock devices (type 3 only).
- Type 5 is for replacements in legacy applications only.
- Type 4A is the standard formulation for normal humidity and temperature.
- Type 3A is suitable for use where resistance to extreme climatic conditions is required.
Types 3A and 4A are for the same applications as the original types, 3 and 4. They contain a reformulated electrolyte that greatly reduces the risk of electrolyte leakage; we recommend using the new formulations instead of the old types in all applications.
Each sensor is laser marked with serial number. Test data available on request.
