    Current Activity :
    Developmental, Experimental and Calibration Work

    (i) Developed 7 Nos. prototype Compact RH Generator based on two pressure technique for humidity calibration to meet the industries requirement in the range of 15 to 95 % RH, with ± 1 % RH stability. These devices were tested in the whole range for its satisfactory performance and these were sold to Various Indian Industries/NABL Laboratries For Rs. 3.7 Lakhs through CFCT Section.

    (ii) Technology Know-How Transferred and Licensed to M/s Belz Instruments Pvt. Ltd., Faridabad (Haryana) on Portable Relative Humidity (RH) Generator dated 20 th July, 2009
    Technology Charges Rs 2.0 Lakhs (Prepared Technology know how Document etc.)
    Technology was developed by: Hari Kishan, Bhikham Singh and Shiv Dutt Sharma

    (iii) Calibration of Digital RHT Sensors/indicators from calibration laboratory & Industries (ECF Rs. 5.9 Lakh) No. of Calibration reports issued = 61

    (iv) In-house Calibration of RHT indicators of all Standards labs in NPL were calibrated (Notional Calibration Charges Rs.15.2 Lakh were saved) No. of Notional calibration reports issued during the period = 113

    (v) Made couple of Resistance and Temperature measurement probes of RT measurement experimental setup for Lab View automation of Superconductivity & Cryogenics Division.
