Services Performed at Your Location
Sentrol Inc. provides on-site calibration, start-up, and system analysis services at manufacturing plants, engineering facilities, and process operations across New England and the Mid-Atlantic. Our factory-trained engineers bring NIST-traceable reference standards and OEM specifications directly to your equipment, so you keep production running while staying accurate, safe, and audit-ready. Headquartered in Carver, Massachusetts, and with regional offices in New Hampshire, Connecticut, and New Jersey, we deliver fast on-site system services when you need them.
LEL Gas Detection System Start-Up and Sensor Calibration
A gas detection system only protects you if it is set up and calibrated correctly from day one. Our technicians handle full start-up of your LEL (Lower Explosive Limit) detection systems and calibrate every sensor to manufacturer specifications. Each service includes zero calibration in clean air or nitrogen, span calibration with certified in-date gas, bump test verification of alarm functions, and sensor response time checks.
These sensors are your first line of defense against combustible gas hazards. A sensor that fails to alarm, or alarms when it should not, creates safety risks, unnecessary evacuations, or OSHA citations. As an authorized service provider for RKI Instruments and other leading gas detection system brands, we calibrate to OEM specifications so your system responds accurately at the setpoints you configured. We calibrate portable and fixed gas detection systems from leading manufacturers, including:
- RKI Instruments
- MSA Safety
- Honeywell / BW Technologies
- Industrial Scientific
- Drager
- Sierra Monitor
- RAE Systems
- Altair
Gas Sensor System Design Advice and Placement
Gas sensor placement can make or break a detection system. Our engineers help you design and position your gas detection network based on the gases you monitor, their density, airflow patterns, and your facility layout. Smart placement decisions before installation save you from costly rework and coverage gaps. With field experience from hundreds of facilities, we deliver reliable coverage that protects your employees and satisfies compliance obligations.
Quarterly and Bi-Annual System Calibrations
Calibration is not a one-time event. Most manufacturers recommend gas detector calibration every 3 to 6 months, with bump tests far more often. We provide scheduled quarterly and bi-annual calibration visits so your systems stay accurate and your records stay current. Routine calibration keeps you ahead of drift before it becomes a safety or compliance problem. Every visit produces complete as-found and as-left documentation, giving you proof your instruments were reading accurately.
Process and Energy Flowmeter Start-Up and Verification/Calibration
Flowmeters measure what matters to your bottom line: product, utilities, and reported emissions. When a flowmeter reads even 1% high or low, the consequences compound into wasted materials, out-of-spec products, billing disputes, or compliance gaps. Our technicians handle on-site start-up, verification, and calibration of your process and energy flowmeters.
Our engineers are factory-trained on ultrasonic, Coriolis, magnetic, thermal mass, and turbine meters from manufacturers including Panametrics, Magnetrol, Rheonik, Flow Technology, and more. As an authorized service provider for several flowmeter manufacturers, we calibrate to OEM specifications. We verify the display reading and analog outputs feeding your control system, and we flag installation issues such as insufficient straight-run piping or air entrainment that undermine accuracy.

Valve and Instrument Performance Analysis
Valves and instruments drift, wear, and fail in ways that are not always obvious until something goes wrong. Our on-site performance analysis evaluates how your valves and instrumentation operate, identifying degradation, calibration issues, or installation problems before they cause a process upset. Catching these problems while equipment is in service lets you plan corrections on your terms. We document our findings and advise on practical fixes.
Combustible Dust Collection System Analysis
Combustible dust is one of the most underestimated hazards in industrial facilities. Our technicians analyze your dust collection systems on-site to evaluate performance and identify conditions that could contribute to a dust-related incident. Because dust accumulation can lead to deflagration or explosion, regulators take it seriously. An on-site analysis gives you a clear picture of your current state and the practical knowledge to address gaps.
Explosion Protection System Selection
The right explosion protection approach depends on your process, the materials you handle, and the equipment you operate. Our engineers help you select the appropriate strategy and components, whether suppression, isolation, venting, or another method suited to your hazard profile. Selecting the right system the first time protects your staff, your facility, and your budget. Our practical expertise helps you make the right explosion protection system decision so you invest in solutions that work.
Explosion Protection System Start-Up
Explosion protection equipment must be commissioned correctly to perform when it counts. Our technicians handle on-site start-up, verifying that every component is installed and configured to function as designed in an emergency. A system that looks installed but is not properly commissioned offers a false sense of security. Our factory-trained engineers confirm your protection is ready to respond exactly as the manufacturer intended.
Explosion Protection System Inspections
Explosion protection systems need regular inspections to stay reliable. Our on-site inspections verify that your equipment remains in proper working condition and continues to meet facility and regulatory requirements. Protection equipment can degrade, drift, or fall out of compliance between major service intervals. Regular checks catch problems early, keep you audit-ready, and ensure your safeguards perform when called on. We document our findings and any recommended corrections.
