Near-Infrared (NIR) Spectroscopy
Online NIR Moisture Analyzer
Non-contact inline moisture control for dryers, conveyors, and powder process lines
This online NIR moisture analyzer uses spectral absorption to convert moisture-related optical changes into stable electrical signals for continuous process control. It supports non-contact measurement through a sight glass, delivers up to 60 checks per second, and helps manufacturers replace manual sampling with faster, more consistent moisture management.

Applications
Industrial Applications
Typical inline installation targets based on ALZRO product positioning and real process requirements.
- Corn starch and modified starch drying
- Grain deep processing and noodle drying rooms
- Soda ash, baking soda, and calcium carbonate lines
- Ceramic powder spray drying
- PVC additives, rubber additives, and pigment intermediates
- Washed sand, sinter mix, wood fiber, and viscose staple fiber
Installation Overview
Mount the sensor head above the process line with the circular NIR lens facing directly downward toward the material surface. Connect the display unit and link to your control system through the available output options. The system supports non-contact measurement, configurable timing, and difficult powder and bulk-material applications.
Best Fit
- Drying sections where manual grab sampling is too slow
- Powder and granule lines that need continuous moisture trends
- Processes where over-drying increases energy cost or quality risk
- Plants that want to network moisture data back to PLC or MES systems
Process Benefits
- Replace manual sampling and subjective hand-feel checks with continuous online values
- Stabilize final product moisture and improve qualified product rate
- Reduce over-drying, energy consumption, and operator workload
- Support tighter process control in harsh, dusty, or high-throughput environments
Integration Options
- RS232 for basic digital communication
- 4-20mA output for retrofit control loops
- Ethernet option for plant networking and data sharing
- Custom Wi-Fi output for wireless projects

Related FAQs
An online moisture analyzer is an industrial instrument that continuously measures moisture content during production, without stopping the line for repeated manual sampling. Unlike laboratory methods that provide delayed spot checks, online analyzers give process teams real-time values they can use to adjust drying, feeding, batching, or quality control earlier. Typical applications include powders, granules, bulk solids, and conveyor-based material handling.
