M/s PREMIER INSTRUMENTS, deals with a wide range of temperature sensing devices, thermocouples and R.T.D sensors We supply Thermocouples and R.T.D of all types, ranges, varieties.All our supplies are with calibration certificates and traceable to national and international standards WE SUPPLY Different types of thermocouples like E, J, K, N, T, S, R, and B. Each type is suitable for a specific temperature range from –201°C to 1700°C.
The construction of each makes it suitable for use in various environments:
Given here is the suitable range for different types of thermocouples
| Thermocouple Conductor Type | Limits of Error (Whichever is greater) | |
|---|---|---|
| Standard | Special | |
| Type K | ±2.2˚C or ±0.75% | ±1.1˚C or ±0.4% |
| Type T | ±1.0˚C or ±0.75% | ±0.5˚C or ±0.4% |
| Type J | ±2.2˚C or ±0.75% | ±1.1˚C or ±0.4% |
| Type N | ±2.2˚C or ±0.75% | ±1.1˚C or± 0.4% |
| Type E | ±1.7˚C or ±0.5% | ±1.0˚C or ±0.4% |
| Type S | ±1.5˚C or ±0.25% | ±0.6˚C or ±0.1% |
| Type R | ±1.5˚C or ±0.25% | ±0.6˚C or ±0.1% |
| Type B | ±0.5% | ±0.25% |
The accuracy of a thermocouple depends on many factors including but not limited to electrical interference and the purity of the metals used.
