Isotech Jupiter 4852 Portable Dry Block Calibrator

Overview

The Isotech Jupiter 4852 is an award-winning portable dry block temperature calibrator engineered by Isothermal Technology Limited (Isotech) for the workshop and field calibration of thermocouples and platinum resistance thermometers. Operating across a working range of 30°C to 660°C in a compact 35mm x 148mm calibration volume, the Isotech Jupiter 4852 is built for technicians who need dependable, repeatable temperature references without the weight, spill risk, or maintenance burden of a liquid bath. Its rapid heating and cooling performance, six-pocket standard insert, and rugged carry-case form factor make it a preferred choice for calibration engineers who move between plant floors, control rooms, and remote sites throughout a single working day.

As the official authorized partner and exclusive regional representative for Isotech, Seven Star LLC proudly supplies the Isotech Jupiter 4852 to calibration laboratories, oil and gas facilities, power plants, and manufacturing sites across Oman and the wider GCC. Every unit shipped through Seven Star LLC is backed by full manufacturer warranty, genuine documentation, and local technical support, giving procurement and quality teams in the Sultanate of Oman a verified supply chain instead of a grey-market import with no traceability.

Measurement Principle and Operating Principle

The Isotech Jupiter 4852 uses a precision-machined metal calibration block heated and cooled by an internal control loop that references either its own onboard sensor (Basic and Site versions) or an independent reference thermometer inserted alongside the unit under test (ADVANCED version). Because the test sensor and the reference sensor sit in the same isothermal block rather than in separate media, the two readings converge on a common, stable temperature with minimal gradient error. The ADVANCED controller adds automatic tuning, automatic temperature cycling, and onboard data logging, allowing an engineer to compare a field thermocouple or RTD directly against a certified reference channel and capture the result without a separate data acquisition system.

Because the calibration medium is a solid block rather than oil, sand, or water, the Isotech Jupiter 4852 eliminates the mess, evaporation, and cross-contamination risks associated with liquid bath calibration. There is no liquid to dispose of, no vapor exposure at the top end of the range, and no waiting for a bath to settle after refilling. The practical result is a calibrator that heats from 30°C to 650°C in around 20 minutes and cools from 650°C back to 150°C in roughly 60 minutes, letting a technician complete several calibration points in a single site visit rather than scheduling separate trips.

Engineering Design of the Isotech Jupiter 4852

Physically, the Isotech Jupiter 4852 is housed in a rugged, top-carry enclosure with a molded protective base and an integrated carrying handle, designed for transport in a vehicle or hard case between sites. The standard insert accepts up to six thermometers simultaneously, with pocket diameters of 4.5mm, 6.4mm, 8.0mm, and 9.5mm at 140mm depth, covering the majority of industrial thermocouple and RTD probe sizes without a custom-bored insert. The ADVANCED variant includes a full-colour, high-resolution display with three independent input channels, allowing a reference thermometer and up to two units under test to be monitored on a single screen.

Connectivity on the Isotech Jupiter 4852 includes a PC interface for I-Cal Easy LOG software, which manages logged calibration data and configures the unit’s automatic cycling routines. The controller electronics are isolated from the heated block by the same enclosure architecture used across Isotech’s 4000-range dry blocks, keeping the operator interface at a safe working temperature even when the block itself is at 650°C. Power input is 115Vac or 230Vac at 50/60Hz, rated at 1000 watts, making it compatible with both regional and international site power without a separate transformer.

Key Features

The Isotech Jupiter 4852 combines a wide operating range with laboratory-grade stability in a genuinely portable package. Its key features include:

• Wide operating range from 30°C to 660°C, covering the majority of industrial thermocouple and RTD calibration points in a single instrument.
• Stability of ±0.015°C at 100°C and ±0.025°C at 650°C on the ADVANCED model, suitable for accredited calibration work.
• Display resolution of 0.01°C across the entire range, giving technicians fine-grained readout for tight tolerance checks.
• Three independent input channels on the ADVANCED controller, supporting simultaneous reference and dual unit-under-test comparisons.
• Automatic temperature cycling and secure onboard data logging, removing the need for a separate logger during multi-point calibration runs.
• Six-pocket standard insert with four pocket diameters, accommodating a broad range of thermocouple and PRT probe sizes without custom tooling.
• Fast thermal response, heating from 30°C to 650°C in approximately 20 minutes and cooling from 650°C to 150°C in roughly 60 minutes.
• Compact, rugged 8.5kg enclosure with integrated carry handle, purpose-built for field transport and site-to-site calibration work.

Industrial Applications

The Isotech Jupiter 4852 is deployed wherever thermocouples, RTDs, and PRTs need routine field verification without pulling instruments back to a fixed laboratory. In Oman’s oil and gas sector, calibration technicians use the Isotech Jupiter 4852 to verify wellhead and pipeline temperature transmitters on site, avoiding the process downtime that a full instrument removal and lab bench calibration would require. Power generation plants, refineries, and district cooling operators across Muscat and the wider Sultanate rely on the same portability to keep control-loop sensors within tolerance between scheduled shutdowns, while food processing and pharmaceutical manufacturers use the dry, contamination-free block to calibrate probes in hygienic environments where liquid baths are undesirable.

As the officially authorized partner for Isotech, Seven Star LLC distributes the Isotech Jupiter 4852 to calibration laboratories and industrial end users throughout Oman and the GCC, including facilities operating out of the Sohar and Salalah economic zones. Engineering and construction contractors commissioning new instrumentation loops, as well as third-party calibration houses serving the regional manufacturing base, specify the Isotech Jupiter 4852 for its combination of accredited-grade stability and genuine field portability, backed by Seven Star LLC’s local stock and technical support.
