Product Overview

The KR‑408A handheld inductive paper moisture tester adopts high‑frequency electromagnetic sensing principle for non‑destructive rapid moisture detection. Integrated sensor‑and‑host design eliminates sample cutting or damaging operations. Users simply place the sensing head against paper‑based materials to get instant moisture‑content readings.

Six‑selectable calibration gears adapt for diverse substrates including plain paper, cardboard, corrugated board, carton boxes and pulp sheets. Compact handheld form factor supports on‑spot production‑line spot‑checks, warehouse incoming‑goods sampling and lab‑quick screening. Widely utilised within pulp‑and‑paper mills, printing workshops, packaging‑manufacturing plants and quality‑inspection departments for real‑time moisture monitoring during manufacturing, storage and material‑receiving workflows.

Core Product Competitive Advantages

1. Non‑Destructive High‑Frequency Inductive Sensing Technology High‑frequency electromagnetic field detects internal moisture without piercing or destroying paper samples. No need for specimen preparation; complete measurement by direct surface contact, greatly boosting on‑site inspection efficiency.
2. Six‑Gear Material‑Matching Calibration Settings Multi‑position adjustment knob provides six calibration gears to match different paper grades, thickness and pulp types. Effectively reduces material‑property‑caused measuring deviation and delivers stable, trustworthy readings for varied paper‑board products.
3. Fast‑Response Digital LCD Readout 3½‑digit clear LCD display refreshes measured value within merely 1 second. Features zero‑point correction button for quick baseline reset before batch‑testing, simple to operate even for less‑experienced field‑operators.
4. Built‑In Wide‑Range Automatic Temperature Compensation Integrated temperature‑compensation module works across‑10 ℃ ~ +100 ℃. It offsets reading drift induced by ambient‑temperature fluctuation, securing measuring precision under varied factory‑site environmental‑conditions.
5. Ultra‑Portable Rugged Hand‑Held Construction Light‑weight 200‑gram body with pocket‑friendly dimensions. Powered by standard 9V laminated battery. Comes with protective hard‑shell carry‑case for safe transport and storage, ideal for frequent moving between production‑lines and warehouse zones.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Take the moisture meter out of protective carry‑case. Install qualified 9 V battery. Power‑on device, perform zero‑calibration with ZERO button according to operating hints. Select proper material‑calibration gear matching the target paper‑board type.
2. On‑Site Specimen Measurement Lay paper / cardboard sample flat. Place the instrument’s inductive sensing head fully onto the material surface, keep steady contact without tilting.
3. Read Moisture‑Content Data Stable moisture‑percentage value appears on LCD within one second. Record reading. For batch‑assessment, take multiple measuring points across different positions of sheet or stack to get representative average‑value.
4. Switch Gear For Different‑Grade Materials When changing to another paper‑board variety, rotate selector knob to corresponding calibration‑gear and re‑check zero‑point before continuing measurements.
5. Post‑Operation Storage Power‑off the instrument after finishing inspection. Remove battery for long‑time idle storage. Wipe sensing‑head surface clean, place unit back into shock‑proof carry‑case.
