Digital Thermo-Hygrometers, Advanced

Quick Answer: The Digital Thermo-Hygrometers, Advanced is the higher-specification member of LabEquip’s digital thermo-hygrometer range: an electronic instrument that shows air temperature and relative humidity, intended for rooms where readings must be tracked and recorded. The title does not list the extra functions, so they are confirmed on request.

Choosing an Advanced Thermo-Hygrometer

The word Advanced in the title separates this model from the plain digital thermo-hygrometer but does not say what it adds. In instruments of this class, the extras that usually matter to a laboratory are a memory of the highest and lowest values since the last reset, adjustable high and low alarms, a clock or date display, an external probe, and data logging with download to a computer. List the functions you need when you enquire, and LabEquip will confirm which this model offers.

Those functions matter wherever a room has written limits. Pharmacy stores, stability chambers, archives, seed banks, balance rooms and instrument rooms often have to show that temperature and humidity stayed within range, not just that they were right when someone looked. A max/min memory or a logger turns a single reading into evidence covering the whole period.

Calibration also matters more when records are kept. Humidity sensors can be checked by sealing them in a small container above a saturated salt solution: saturated sodium chloride holds the air close to 75 % relative humidity at room temperature, and saturated magnesium chloride close to 33 %, according to the reference values Greenspan published in 1977. A reading far from these values means the instrument needs adjustment or service.

Specifications

Care & Handling

• Download or write down stored readings before resetting the memory or changing the battery.
• Check the humidity reading with a saturated salt test at a regular interval and note the result.
• Mount the advanced digital thermo-hygrometer where it represents the room, not beside a door, window or air vent.
• Keep spare batteries on hand so that logging is not interrupted.

Applications

• Recording conditions in pharmacy stores and dispensaries
• Tracking humidity in archives, herbaria and seed stores over weeks
• Monitoring balance rooms and instrument rooms where stable conditions matter
• Long-term classroom projects comparing the indoor climate through the seasons

Why Choose LabEquip

Pharmacy colleges, hospital stores, archives and quality-control labs choose an advanced model when an inspector or a procedure expects a continuous record rather than a spot reading. LabEquip lists it in its General Lab Products range; send us the functions your procedure requires.

Frequently Asked Questions

What makes this thermo-hygrometer Advanced?

The title does not list the extra functions. In this class of instrument they usually include max/min memory, alarms, a clock, an external probe or data logging. Tell LabEquip which you need and the model’s functions will be confirmed.

Why keep a continuous record instead of spot readings?

A spot reading shows conditions only at that moment. A memory or logger shows whether the room went out of range overnight or over a weekend, which is what stores with written limits must demonstrate.

How can I check the humidity sensor?

Seal the sensor in a small container above a saturated salt solution for several hours. Sodium chloride gives close to 75 % relative humidity and magnesium chloride close to 33 % at room temperature, according to Greenspan’s 1977 reference values.

Is the humidity reading affected by temperature changes?

Yes. Relative humidity depends on temperature, so a room that warms by a few degrees shows a lower humidity with no change in moisture. Always read the two values together.

Where should it be installed in a store room?

At shelf height in the part of the room where the stock is kept, away from doors, windows, lights that give off heat and air-conditioning outlets.

Can it replace a calibrated reference instrument?

It is a monitoring instrument. Where a procedure demands traceable measurements, check it against a calibrated reference and keep a record of the comparison.
