Description

Isotech Calisto 4953 Temperature Calibrator Repair

The Isotech Calisto 4953 Temperature Calibrator is a temperature calibration source. Whether it heats a metal block or stirs a liquid, the specification that matters is not whether it reaches a setpoint but how uniformly and how stably it holds one, because that is what the probes under test actually see.

June Company repairs and calibrates the Isotech Calisto 4953 Temperature Calibrator for calibration laboratories, instrument technicians, and process metrology teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common Isotech Calisto 4953 Temperature Calibrator problems we fix

Heater element failure or slow heating.
Will not reach low setpoints.
Control loop unstable or overshooting.
Stirrer or circulation faults on liquid baths.
Well, insert or probe port damage.
Display, keypad or front-panel faults.
GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
Stability or uniformity outside specification – a source at the right average temperature can still vary enough across the well to move a reading, and nothing on the display reveals it.

FAQs

Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.

It reaches setpoint but my readings still disagree. What is wrong? Usually uniformity rather than setpoint. The source can be at temperature on average while varying enough across the well to move a reading.

Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.

Shipping & Returns

Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.

Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.

Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.

Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
