Clamping system Pt 1000

Quick Answer: The Clamping System Pt 1000 is a Pt1000 probe clamp: a rod-mounted holder that keeps a Pt1000 temperature probe upright at a set depth in a stirred liquid. The listing photograph shows a support rod with a black clamp block and a handle-shaped holder carrying a slim probe tube.

Why a Pt1000 Probe Needs a Proper Clamp

Many hotplate stirrers and heating blocks can control temperature from an external Pt1000 sensor placed in the liquid, rather than from the top plate. That gives a far more accurate sample temperature, but only while the probe stays where it should: submerged, clear of the stir bar and away from the hot vessel wall. A loose probe that slides up out of the liquid reads air temperature, and the controller responds by heating harder.

The clamping system in the photograph solves that with two parts. A black clamp block grips an upright support rod at any height, and a horizontal holder with a grip handle carries the probe vertically. Loosening the clamp lets the probe be raised or lowered to suit the liquid level, and tightening it locks the position for the run.

The listing does not state the probe diameter the holder accepts or the rod diameter the clamp fits, so pair it with a probe and rod known to match, such as the PT 1000 stainless steel temperature probe sold alongside it.

Specifications

Applications

• Probe-controlled heating of a stirred beaker to a fixed setpoint
• Holding the probe in a flask on a heating block during a long reaction
• Logging the temperature of a water or oil bath during a practical
• Repeating a set-up exactly between runs by marking the probe height

Care & Handling

• Set the probe tip at least a finger’s width above the stir bar and away from the glass wall
• Tighten the clamp by hand; overtightening can crush a thin probe sheath
• Keep the handle and clamp block away from the heated top plate
• Wipe the holder after use so dried residue does not grip the probe

Why Choose LabEquip

The clamping system is usually added to an order when a lab starts controlling hotplate temperature from a probe in the liquid. LabEquip can supply it with a matching probe and support rod from the general lab products range and, if you contact us, check that all three suit your stirrer.

Frequently Asked Questions

What is a Pt1000 probe clamp used for?

It holds a Pt1000 temperature probe steady at a chosen depth in the liquid, so a hotplate stirrer or heating block can control the sample temperature accurately.

Where should the probe tip sit in the liquid?

Fully submerged, above the stir bar and away from the vessel wall and bottom. That position gives a reading close to the bulk liquid temperature.

What happens if the probe slips out of the liquid?

The controller reads a lower temperature and keeps heating, which can overheat the sample or boil it dry. A firm clamp prevents that.

Does the clamp work with other probe types?

It is designed around a Pt1000 probe. A thermometer or another probe of similar diameter may fit the holder, but check the diameter first.

Which support rod does the clamp need?

It fits an upright rod of suitable diameter, often one mounted on the stirrer. Tell us your stirrer model and we will confirm a compatible rod.

Can the clamp be left on the rod permanently?

Yes. Many labs leave it in place and simply adjust the height for each vessel, which saves set-up time and keeps probe depth consistent.
