High-Frequency Moisture Meter - MS350A Powder and Pellet Tester

Powder, Pellet And Soil Testing

The MS350A high-frequency moisture meter is built for soil, silver sand, chemical combination powder, coal powder, pellets, and other powder materials. The 280 mm needle supports inserted checks in bags, piles, and sampling containers.

MS350A and MS350: compare probe reach

The MS350A has a 280 mm needle; the MS350 powder moisture meter uses a 230 mm probe. Both require four AAA batteries. Choose the probe that reaches the intended sampling point, then match the material and measuring mode to the sample. A longer probe does not establish greater accuracy.

Needle Probe Functions

• 0–60% measuring range with 0.1% resolution.
• 280 mm needle for deeper material checks.
• Backlit 4-digit LCD keeps readings visible.
• Manual power-off, auto power-off, data hold, and low-battery alert are included.
• Compact AAA battery-powered body supports portable use.

Is MS350A Suitable for Your Material?

Use the MS350A when the sample matches the named soil, silver sand, chemical combination powder, coal powder, or pellet groups and an inserted 280 mm needle suits the measurement point. The displayed 0–60% range does not mean every material responds identically. Keep sample type, insertion depth, and measurement conditions consistent when comparing readings. For other samples, compare the wider moisture meter collection.

MS350A vs DM300C

Choose by material and workflow rather than resolution alone. The MS350A uses a 280 mm needle and four AAA batteries. The DM300C powder moisture meter has an approximately 220 mm probe, uses a 9 V 6F22 battery, and provides multiple settings for chemical powders, coal powder, dyes, and resins. Neither model should be treated as universally suitable for every powder.
