5 Best Maintenance Software Tools for Checkweighers & Metal Detectors (2026 Review)

"The reject arm fired, but the metal-contaminated box stayed on the line."

This is a Class 1 Recall scenario. End-of-Line inspection equipment (Checkweighers, Metal Detectors, X-Ray) is the last line of defense.

These machines are sensitive. Vibration from a worn conveyor belt can cause "False Rejects." A dirty photo-eye can cause "Reject Failure."

Legacy maintenance (paper logs and annual certification) is risky. It creates a "Gap of Uncertainty" between checks.

In 2026, Inspection Maintenance Software is rigorous. It connects to the Reject Verification Sensor. It enforces the Hourly Test. It monitors Giveaway Trends.

Here are the 5 best tools to keep your product safe and legal.

The Comparison Matrix (2026)

1. Fabrico: The "Audit-Proof" Platform

Verdict: The best choice for factories that want to link Food Safety Tests directly to Machine Performance.

Fabrico treats the Metal Detector as a safety device. We digitize the "test wand" checks and connect to the PLC to count false rejects.

Why It Wins on Inspection:

• Digital CCP Logs: Fabrico enforces the schedule: "Perform Metal Detector Test every 60 minutes." The operator cannot close the task without inputting the test result. If they miss a check, the Quality Manager gets an alert.

• Giveaway Monitoring: Connects to the checkweigher to track "Average Weight." If the machine starts overfilling (Giveaway), Fabrico triggers a "Calibrate Filler" task upstream.

• Reject Analysis: If the metal detector triggers 50 times in an hour (False Rejects), Fabrico flags a maintenance issue (e.g., "Check Belt Tracking" or "Electrical Noise").

Best For: Food, Beverage, and Pharma packaging lines.

2. Mettler Toledo (ProdX): The "OEM" Brain

Verdict: The absolute standard if your line is full of Mettler Toledo / Safeline equipment.

ProdX is a powerful data management software designed to centralize inspection data.

Pros:

• Central Control: You can change the "Product Setup" (recipes) on all metal detectors from one PC.

• Compliance Reports: Generates audit-ready PDF reports showing exactly when every test was performed.

Cons:

• Hardware Locked: Optimized for Mettler. Integrating your legacy Anritsu or Fortress units requires expensive drivers.

• Not a CMMS: It tracks the data, but it doesn't help you schedule the conveyor belt replacement or manage the spare load cell.

Best For: High-end lines standardized on Mettler.

3. Loma Systems (TRACS): The "Reporting" Tool

Verdict: Essential for users of Loma Metal Detectors and X-Rays.

TRACS focuses on reporting efficiency and quality events.

Pros:

• Batch Reporting: Links reject statistics to specific production batches.

• Live Visibility: Shows the status (Run/Stop/Error) of every machine on the floor.

Cons:

• Siloed: Like ProdX, it is an inspection tool, not a plant-wide maintenance tool. It identifies the problem, but doesn't manage the fix.

Best For: Bakeries and Meat plants using Loma.

4. Poka: The "How-To" Guide

Verdict: The best tool for training new operators on How to Perform the Test.

Testing a metal detector correctly (placing the wand in the center of the aperture) is a skill. Poka teaches it.

Pros:

• Video SOPs: Operators can watch a 30-second video on the tablet right at the machine before doing the test.

• Standardization: Ensures every shift performs the test exactly the same way.

Cons:

• Manual Data: It doesn't connect to the machine to verify the test passed. It relies on the operator's integrity.

Best For: Training and workforce compliance.

5. MaintainX: The "Compliance" Log

Verdict: The simplest way to replace the paper "HACCP Log" on the clipboard.

MaintainX creates a digital record of the test.

Pros:

• Digital Signature: Captures the operator's e-signature and timestamp for every test.

• Audit Search: "Show me all Metal Detector checks for Line 1 in July." Done in seconds.

Cons:

• No Interlock: It allows the operator to log "Pass" even if the machine didn't actually trigger. It lacks the PLC integration of Fabrico.

Best For: Small food plants simplifying audits.

Conclusion: Trust but Verify

Inspection equipment is only as good as its last test.

• If you have Mettler, use ProdX.

• If you have Loma, use TRACS.

• If you need a Unified Platform that enforces CCP Checks, monitors Giveaway, and manages Repair Workflows, Fabrico is the 2026 solution.
