Tempsens is India's largest maker of contact and non-contact temperature sensors by revenue (about 10.5% market share), and also makes electrical heating solutions and specialised cables for industrial process customers.
The price band is ₹285 to ₹300 per share. The minimum lot is 50 shares, so a retail investor needs about ₹15,000 to apply for one lot at the upper band.
GMP climbed sharply through the week — from ₹154 (51%) on August 17 to ₹313 (104%) by the final subscription day, August 24. That implies a listing price near ₹613, though GMP is an unofficial, unregulated indicator and the actual listing price can differ meaningfully.
Yes — the issue was subscribed 21.69 times overall, with the non-institutional (NII) portion leading at 52.98 times and retail at 18.73 times.
Anand Rathi rated it 'Subscribe – Long Term', citing revenue growth and international expansion, while also flagging that the valuation at the upper price band leaves limited room for error. KC Securities also recommended subscribing. As with any IPO, strong GMP and brokerage support aren't guarantees — weigh the valuation (P/E near 35x) against your own risk tolerance.
