Re: Battery woking of dust sampler

Dear sir,

I am L P Singh, lecturer (Sr Scale) in department of Industrial and Production Engineering at Dr B R Ambedkar National Institute of Technology Jalandhar. We have purchased dust sampler Leland Legacy Pump (Cat No. 100-3002k) and Personal environment monitor (cat. No. 761-203 B) from Environmental Pvt Ltd. Hyderabad vide invoice dated SWAN19-03 against our purchase order 26-02. From the very first day the Instrument is giving problem. neither the pump nor the battery is not working properly i.e. pump is not working in the actual dusty environment and battery is showing only one or two mars after a charging of even 48 hour. Then i complaints many times to the concerned persons then after a few months an Engineer came from M/S Environmental Pvt Ltd. and took the instrument along worth him and said that they will report back within a week. After that nobody replied, then after 15 days i called up the concerned persons said that they are in touch with the manufacturer, subsequently I again called on 23-7 but he do not attended our call. Sir it is Now July is almost over but still no response have been observed.

Sir i am doing Ph D in Occupational health and Environment, I was suppose to collect data by using the instrument during April and write a paper for Journal by this time and but Instrument is not working and the company is not even telling whether the instrument will be replaced or repaired. Sir i have almost lost my 4-5 months, as my duration is depleting day by day and my further work is also being hampered i am totally tucked up. I humbly request you to kindly look up in this matter so that i can get instrument and record my data, and also my time loss should be compensated. I shall be very highly oblized.

Kind Regards

L P Singh
