Tempsens Instruments IPO Subscription Status Day 1 – Live Updates & Key Details

Tempsens Instruments opened its IPO for subscription on August 20, 2026. Incorporated in 1990, the company is a leading thermal engineering business and specialised cable manufacturer, designing and manufacturing customised temperature sensing devices, electrical heating systems, and specialised cables across industrial applications. Its offerings span three verticals, temperature sensing solutions like thermocouples, resistance temperature detectors, infrared pyrometers, and furnace monitoring cameras, along with electrical heating solutions and specialised cables, exported to more than 80 countries including the UAE, Germany, and Poland.

This is a ₹650 crore IPO, made up of a ₹95 crore fresh issue and an offer for sale of ₹555 crore. Part of the money raised goes into the business, while the rest goes to existing shareholders selling part of their stake.

Price band is set at ₹285 to ₹300 per share. Lot size is 50 shares, so retail investors need ₹15,000 to apply at the upper end. The issue closes August 24, and listing is expected August 28 on both BSE and NSE.

Category-wise Breakdown on Day 1

Figures as of 5:27 PM, August 20, 2026 (Day 1 close, consolidated bid details), per NSE data. The issue received bids for 7.48 crore shares against 1.52 crore shares on offer.

What Day 1 Numbers Indicate

NII has driven this opening-day surge in dramatic fashion, closing at 9.96x, with small HNIs (17.08x) running well ahead of big HNIs (6.39x). This kind of strong non-institutional response on day one itself, rather than the more typical last-day rush, signals real investor conviction in the listing.

Retail closed comfortably oversubscribed too, at 5.55x, and the employee quota ran even hotter at 7.59x. QIB, at just 0.04x, has barely registered at this stage, which is entirely normal, institutional investors almost always place the bulk of their bids only in the closing day or two of a bidding window, once they've had time to assess how the rest of the book has filled up.

Getting the entire issue fully subscribed within an hour of opening, and closing Day 1 at nearly 5x, points to strong across-the-board investor appetite for this issue right from the start, a fairly rare occurrence for a mainboard IPO of this size.

Tempsens Instruments IPO Subscription Status – Day 1

With four days of bidding still ahead, and NII, retail, and the employee quota all already comfortably oversubscribed by Day 1's close, the main thing to watch is how far QIB builds over the coming days. Institutional bids typically arrive in a rush in the final one to two days, so expect the sharpest movement closer to the August 24 close.

Tempsens Instruments IPO - Allotment and listing date

Should You Apply for Tempsens Instruments IPO?

A few things worth weighing before you decide:

• It's a mix of fresh issue and offer for sale, with the ₹95 crore fresh issue going into the company, while the larger ₹555 crore OFS portion goes to existing shareholders selling part of their stake.
• Tempsens Instruments is a well-established thermal engineering and specialised cable manufacturer, with three decades of experience and a global export footprint spanning more than 80 countries.
• QIB gets the largest allocation at 50% of the issue, with retail at 35% and NII at 15%, a fairly standard structure for a mainboard industrial manufacturing business of this scale.
• Day 1 demand has been led by NII (9.96x) and the employee quota (7.59x), with retail also comfortably oversubscribed at 5.55x, while QIB has yet to meaningfully pick up, typical for this early in a five-day bidding window.
• Promoter and promoter group holding will come down from 80.51% to 65.67% after the issue.
