Electronic Moisture Analyzer

Electronic Moisture Analyzer

Excess moisture in powders and granules causes capping, sticking, and other tableting defects. Our Electronic Moisture Analyzer measures moisture content directly in pharmaceutical powders, granules, and tablets.

Key Features

  • Halogen-based loss-on-drying (LOD) for fast moisture determination
  • 0–100% moisture range, ±0.5% accuracy, 60–160 °C heating
  • Compact benchtop design for lab and manufacturing floor use

Applications

  • Raw material and granule moisture QC before tableting
  • Investigating capping/sticking defects linked to moisture content

How to choose a moisture analyzer for pharmaceutical powders

A halogen moisture analyzer heats the sample with a halogen lamp and weighs it continuously; the weight lost on drying (LOD) gives the moisture content. The HQ Series electronic moisture analyzer in the Huanghai Pharmaceutical Instruments catalog measures 0–100% moisture with ±0.5% accuracy at 60–160 °C, which suits powders, granules and tablets before and after compression. Choose HQ-501, or HQ-501 CE where CE marking is required.

Model comparison

Model Method Range and accuracy Heating Certification
HQ-501 Halogen loss on drying 0–100%, ±0.5% 60–160 °C (±2 °C), 0–120 min Standard version
HQ-501 CE Halogen loss on drying 0–100%, ±0.5% 60–160 °C (±2 °C), 0–120 min CE certified

How to choose

  • Fast routine checks of powders and granules, for example before tableting: a halogen LOD analyzer gives a result in minutes.
  • Water specifically, trace water, or samples that lose other volatiles on heating: use Karl Fischer titration (KFT-50VC) instead.
  • Instruments used or resold in the EU: choose HQ-501 CE.
  • Drying program: fixed-time or automatic end point, fixed-weight or dry-mass drying mode, 95 mm sample pan, RS232 output; 290 × 180 × 140 mm.

Pharmacopoeia and compliance

Loss on drying measures all volatile matter and is a fast method for incoming-material and in-process checks; Karl Fischer titration measures water specifically. HQ-501 CE carries CE certification.

Frequently asked questions

How does a halogen moisture analyzer work?
It heats the sample with a halogen lamp and weighs it continuously; the weight lost on drying gives the moisture content.

What are the key specifications?
Range 0–100% moisture, accuracy ±0.5%, heating 60–160 °C (±2 °C), heating time 0–120 min, 95 mm sample pan, RS232 output.

Is a CE-certified version available?
Yes. HQ-501 CE offers the same halogen moisture analysis with CE certification.

Halogen moisture analyzer or Karl Fischer titrator?
Loss on drying measures all volatiles and is fast for powders and granules. Karl Fischer titration measures water specifically and reaches trace levels; see the KFT-50VC Karl Fischer titrator.
