## Pressure gauges
- [Pressure gauges](https://www.pioneergauges.in/pressure-gauges.html): Pioneer makes Bourdon tube pressure gauges in Pirangut, Pune: all-stainless with SS 316 tube and socket, dials from 40 to 250 mm, ranges from 0–1 to 0–600 kg/cm² plus vacuum and compound, ±1% FSD as per IS 3624. Below are the types we supply and where each one fits.
- [Stainless Steel Pressure Gauge](https://www.pioneergauges.in/stainless-steel-pressure-gauge.html): Pioneer's all-stainless Bourdon tube pressure gauge has an SS 316 Bourdon tube and socket, an SS 304 movement and an SS 304 case. It is made in Pirangut, Pune with dials from 40 to 250 mm, ranges from 0–1 to 0–600 kg/cm² plus vacuum and compound, and ±1% FSD accuracy as per IS 3624.
- [Glycerine Filled and Weatherproof Pressure Gauge](https://www.pioneergauges.in/glycerine-filled-pressure-gauge.html): A glycerine filled pressure gauge has its case filled with glycerine (or silicone oil) so the pointer stays steady on pulsating or vibrating lines. Pioneer makes it on the all-stainless build: SS 316 Bourdon tube, SS 304 case sealed to IP 65 / IP 67 with a blow-off disc, dials from 40 to 250 mm and ±1% FSD accuracy as per IS 3624.
- [Commercial Pressure Gauge](https://www.pioneergauges.in/commercial-pressure-gauge.html): Pioneer's commercial pressure gauge is the economical choice for indoor, non-corrosive service: an MS powder-coated case with a brass measuring system and movement, 40 to 100 mm dials, ranges from 0–1 to 0–600 kg/cm² and IP 54 protection. It is widely used by OEMs, compressor and hydraulic machine builders.
- [Test Gauge (±0.25% FSD)](https://www.pioneergauges.in/test-gauge.html): A test gauge is a high-resolution reference gauge used to check working gauges and to witness hydrostatic tests. Pioneer's test gauge reads to ±0.25% FSD as per IS 3624, has an SS 316 Bourdon tube and socket in an SS 304 case, and comes with 100, 150, 200 or 250 mm dials and a knife-edge pointer for fine reading.
- [Digital Pressure Gauge](https://www.pioneergauges.in/digital-pressure-gauge.html): Pioneer supplies battery-powered digital pressure gauges with a backlit LCD, 0.5% FS accuracy, selectable units and a 316L isolation diaphragm, covering vacuum (−100 kPa) up to 100 MPa. Use one where a clear numeric reading, peak hold or unit switching matters more than a dial.
- [Differential Pressure Gauge](https://www.pioneergauges.in/differential-pressure-gauge.html): A differential pressure gauge reads the difference between two pressures, such as across a filter, strainer, coil or flow element, on one dial. Pioneer supplies analog (dial) DP gauges in stainless steel with dual bottom connections, a 0–100 mbar diaphragm-operated remote-seal DP gauge with a 150 mm SS 304 case, and digital DP indicators.
- [Magnehelic Gauge](https://www.pioneergauges.in/magnehelic-gauge.html): A low differential pressure gauge, often called a Magnehelic-type gauge, reads very small air pressure differences in pascals. Pioneer supplies it in ranges from 0–60 Pa to 0–8 kPa, including 60–0–60 Pa, on a 100 mm dial with ±3% of full-scale accuracy, for clean rooms, AHU filters, ducts and fume hoods.
- [Diaphragm Seal Pressure Gauge](https://www.pioneergauges.in/diaphragm-seal-pressure-gauge.html): A diaphragm seal pressure gauge keeps the process away from the gauge: a flexible diaphragm transmits pressure through a fill fluid, so slurries, viscous, crystallising or corrosive media cannot block or attack the Bourdon tube. Pioneer supplies diaphragm gauges with a 100 mm SS 304 case and blow-out device, dry or liquid filled, with materials confirmed at quotation.

## Temperature gauges
- [Temperature gauges](https://www.pioneergauges.in/temperature-gauges.html): Pioneer makes all-stainless bimetallic temperature gauges with 100 to 250 mm dials and ranges from −50 to +50 °C up to 0 to 600 °C, ±1% FSD as per EN 13190, in bottom, back and every-angle mounting, and supplies digital Pt100 gauges and SS thermowells to go with them.
- [Bimetallic Temperature Gauge](https://www.pioneergauges.in/bimetallic-temperature-gauge.html): Pioneer's bimetallic temperature gauge is an all-stainless dial thermometer: SS 304 case with bayonet bezel, 8 mm SS 316 stem with immersion length up to 300 mm, dials of 100, 150, 200 and 250 mm, ranges from −50 to +50 °C up to 0 to 600 °C and ±1% FSD accuracy as per EN 13190. It needs no power and is made for bottom, back or every-angle mounting.

## Tools
- [Gauge range selector](https://www.pioneergauges.in/gauge-range-selector.html): Interactive tool: recommends the standard pressure or temperature gauge range for a given working value.
- [Pressure unit converter](https://www.pioneergauges.in/pressure-unit-converter.html): Interactive converter between kg/cm², bar, psi, kPa, MPa, Pa, mbar, mmH2O, inH2O, mmHg, inHg, atm.

## Guides
- [How to select a pressure gauge](https://www.pioneergauges.in/how-to-select-a-pressure-gauge.html): Choose the range so normal pressure sits near mid-scale (about twice the working pressure, maximum below 75%), a dial size readable from where people stand, SS 316 wetted parts unless the service is clean and dry, liquid filling for pulsation, a siphon for steam and a diaphragm seal for corrosive or viscous media.
- [Glycerine filled vs dry pressure gauge](https://www.pioneergauges.in/glycerine-filled-vs-dry-pressure-gauge.html): Use a glycerine filled gauge wherever the pressure pulsates or the pipe vibrates: pumps, compressors, hydraulics. Use a dry gauge on steady lines, on oxygen and oxidising service, and where cost matters more than pointer steadiness. Choose silicone instead of glycerine in cold climates.
- [IS 3624 and EN 837-1: pressure gauge standards](https://www.pioneergauges.in/is-3624-vs-en-837-1-pressure-gauge-standards.html): IS 3624 is the Indian standard for Bourdon tube pressure and vacuum gauges; EN 837-1 is the European equivalent, used on many export and multinational projects, with EN 837-2 giving selection and installation advice. Both define accuracy as a percentage of full scale. Pioneer's working gauges are ±1% FSD as per IS 3624 and test gauges ±0.25% FSD.
- [How to select a temperature gauge and thermowell](https://www.pioneergauges.in/how-to-select-a-temperature-gauge-and-thermowell.html): Pick a range that puts normal temperature in the middle third of the dial, a 100 or 150 mm dial, every-angle mounting if the final orientation is uncertain, a stem long enough to reach the flow, and always a thermowell: barstock SS 316 for steam, process and high-velocity lines, fabricated SS for HVAC and utility water.
