Designed for rugged field and plant use, it features a protective rubber boot, backlit display, and supports a wide range of thermocouple and RTD types. Its smart auto-detection and EZ-CHECK™ memory functions streamline calibration and troubleshooting, making it an indispensable tool for temperature sensor professionals. ## Description Automated Thermocouple & RTD Calibrator PIE is pleased to introduce the New Model 525B which replaces the PIE Model 525. This moves our Dual Thermocouple & RTD calibrator to the PIE Evolution enclosure with a rubber boot, tilt stand, 4 "AA" batteries and backlit display. Not only did we move the product into the new enclosure, we made a number of other improvements! Thermocouple Connections Simulating or reading thermocouples requires the use of thermocouple or extension grade thermocouple wire. Plug thermocouple wires into the miniature thermocouple jack or place bare thermocouple wires onto the brass block under the screws. The PIE 525B has two banana jacks (1+ & 2-) mounted in the top end of the housing. These are not temperature compensated and are to be used only for millivolt signals. Screw terminal for T/C wire plus miniature T/C socket Isothermal block with ±0.05°C Cold Junction Sensor Banana jacks for 2, 3 & 4 wire RTD RTD Connections Simulating or reading RTDs uses copper wire. Plug 2, 3 or 4 wires into the corresponding jacks on the calibrator. For RTD source the PIE 525B simulates the (+) RTD from jacks 1 & 4 and the (-) RTD from jacks 2 & 3. When reading an RTD sensor the PIE 525B uses patented circuitry to automatically detects if 2, 3 or 4 wires are connected. This is helpful to troubleshoot sensor connection. Troubleshooting an RTD Sensor When measuring an RTD sensor the PIE 525B uses patented circuitry to automatically detect 2, 3 & 4 wire connections. This may also be used as a troubleshooting tool to determine if any wires from the sensor are broken. Here is an example of the 525B reading a sensor with all 4 wire connected. Here is an example where connections are made to a 4 wire sensor and the PIE 525B indicates that only Wires 1, 2 & 4 are connected. There may be a loose connection or a break in wire 3 somewhere between the sensor and the 525B. ## Features - Easy to use With the PIE 525B you can check and calibrate all your thermocouple and RTD instruments and measure temperature sensors. - Take it into the shop, plant or field Carry it without worry - it comes protected with a rubber boot and rugged, low profile switches. Easy to operate even in the dark areas of the plant with the backlit display. - Calibrate thermocouple instruments to 0.1 & 0.01 °F & °C The PIE 525B works with the thermocouples you use including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Or calibrate from -13.0000 to +80.0000 mV. - Calibrate RTD instruments to 0.1 & 0.01 °F & °C Stop carrying around a decade box and RTD resistance tables. The 525B works with the RTDs you use including Platinum 10, 50, 100, 200, 500 & 1000 Ohm (alpha = 3850), Platinum 100 Ohm (alpha = 3902, 3916, 3926), Copper 10 & 50 Ohm, and Nickel 120 Ohm. Or calibrate from 0.000 to 400.000 and 0.00 to 4000.00 Ohms. - Fast calibration with automatic output stepping Easily set any value quickly to within 0.1° or 0.01° with the adjustable digital potentiometer “DIAL” plus store any three temperatures for instant recall with the EZ-CHECK™ switch. Choose between 2, 3, 5, 11 steps and ramp to automatically increment the output in 100%, 50%, 25%, 10% or 5% of span. Select step time from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NAS913S | | Best Sellers Rank | #991,366 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #44 in Temperature Calibrators | | Brand Name | Piecal | | Included Components | 525B | | Item Dimensions | 1 x 1 x 1 inches | | Item Weight | 16 ounces | | Manufacturer | Piecal | | Model | 525B | | Part Number | 525B | | Power Source | See Product Details | | Style Name | Foldable UV/White Beam | | UPC | 642896275829 | | Unit Count | 1 Count | ## Product Details - **Brand:** Piecal - **Item Weight:** 16 ounces - **Item dimensions L x W x H:** 1 x 1 x 1 inches - **Power Source:** See Product Details - **Style:** Foldable UV/White Beam ## Images ![PIE 525B Automated Thermocouple & RTD Calibrator - Image 1](https://m.media-amazon.com/images/I/51o89U-YA-L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/41098643-pie-525b-automated-thermocouple-and-rtd-calibrator](https://www.desertcart.gr/products/41098643-pie-525b-automated-thermocouple-and-rtd-calibrator) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-05*
