Note : 1 In case of T/C J/K type analog output target temperature should be greater than ambient temperature.
2Please do not keep sensor head in hand during the measurement of temperature for better accuracy.
1 At ambient temperature 23± 5°C, ε=1 and response time = 600msec.
2 For ambient temperature (sensor head) <18°C and >28°C
