I am Shyam, a nuclear Scientist from India and a Professor to engineers.
This message is a special and limited help to learning Engineers and not an offer of business for companies.
I have collection of HS1101 Humidity Sensors of Humirel with me which Humirel gives at $15 each in lots of 5 numbers plus shipping charges making it $120 for 5 numbers.
I will like give the same HS1101 sensors in double quantity of 10 numbers for the price of US$120 by T/T as long as my collection of 500 sensors lasts. If you are sending a check then include $20 more for processing charges for checks (US$140 total). Make the check in the name of Sensors Technology Private Limited, Address: AM-51, Deen Dayal Nagar, Gwalior, MP 474020, India. Phone +91-751-2470680 Fax +91-751-5045715.
I will pay for FedEx shipping charges to your place which you know will be high. You may get the sensors in about 7 days after I get your payment.
Catalog is on my web site http://sensorstechnology.tripod.com/HS1101.pdf
