Halogen Moisture Analyzer

Halogen Moisture Analyzer The SL-V series halogen moisture analyzer employs the "drying method" using a highly efficient drying heater - a high-quality cyclic halogen light. This lamp quickly and evenly heats the sample, continuously drying its moisture content. The measurement process is swift, automatic, and straightforward.

Feature :

Real-time display of measurement results including humidity value, solid content, water mass to dry weight ratio, moisture mass to dry weight ratio, initial sample value, final value, measurement time, final temperature value, trend curve, and more.

Capable of transmitting data to a printer, computer, PLC, etc. via an RS232 serial port.

Suitable for rapid moisture measurement in solid, liquid, and powder states within minutes (for most samples).

User-friendly operation, integrates multiple heating modes, and is versatile in application.

Widely demanded and employed across industries such as grain, food, agriculture, chemical, plastics, new energy, new materials, pharmaceuticals, scientific research, and testing.

FAQ

Q1: What does a halogen moisture analyzer measure in plastics testing?

It measures the moisture content in plastic pellets and powders. Excessive moisture causes bubbles, silver streaks, and cracking in molded parts, so it must be tested before raw materials enter production.

Q2: What is the difference between halogen moisture analysis and the traditional oven method?

Both use the loss-on-drying principle, but efficiency differs greatly:

·Oven method: takes hours or even overnight, labor-intensive

·Halogen method: results in minutes (3–10 min for most plastics), fully automatic, real-time display

Halogen analyzers are ideal for fast incoming QC and batch inspection on the production floor.

Q3: Is the SL-V series accurate enough for plastics testing?

The SL-V series offers 0.001 g (1 mg) readability (some models up to 0.0001 g), with moisture resolution of 0.01%. It fully meets the moisture testing requirements of PE, PP, PVC, PA, PET, ABS and other common plastics.

Q4: Can plastic pellets be tested directly? Do they need to be ground?

It depends:

·Pellets: Can be tested directly, but moisture release is slower — extend drying time or select a suitable heating mode for best results.

·Powders: Larger surface area speeds up drying for faster results.

·Hygroscopic materials (PA, PET): Grinding is recommended for more accurate results; seal samples properly before testing to avoid ambient moisture pickup.

Q5: How long does a test take?

Most plastic samples are done in 3–10 minutes. Actual time depends on sample form (powder < pellets < chunks), initial moisture level, and selected temperature/end-point mode.

Q6: How should I set the temperature? Does it vary by plastic type?

Yes — incorrect temperature can cause deviations or sample degradation:

·PE, PP: typically 105–120°C

·PVC: around 105°C (high temperatures may release small molecules and skew results)

·PA, PET: 120–150°C (refer to the material's Tg and decomposition temperature)

·Always follow the relevant national standard or supplier datasheet for specific materials.

Q7: Besides plastics, what other samples can it test?

The SL-V series handles solids, liquids, and powders, and is widely used in grain, food, agriculture, chemicals, new energy, new materials, pharmaceuticals, and scientific research — one instrument, many applications.
