Refrigerator & Freezer Monitoring for Healthcare Facilities.

Your medication refrigerators and freezers are your most-used critical storage units. PharmaWatch watches every one of them continuously — catching temperature drifts, equipment failures, and open doors before product is ever at risk.

Real-Time Alerts & Predictive Equipment Failure Detection
PharmaWatch reads the early warning signs your staff can't — compressor cycle frequency, recovery duration, performance trends. You get alerted before a temperature excursion becomes a product loss.

Automated Compliance Records
Every reading, excursion, and alert response is logged automatically in a tamper-evident audit trail that supports compliance with FDA 21 CFR Part 11. When an inspector walks in, your records are already there.

Why we’re different

There’s a Reason Facilities Choose Us.

A close-up image of a textured surface, featuring shades of blue and black with a pattern that suggests depth and dimension. The design is abstract, resembling waves or brush strokes within the color gradient.
No Physical Buffers Near Your Samples

Other systems place a glycol bottle or glass beads next to the sensor to reduce false alarms. That's a contamination risk in a sterile pharmacy, a cleanroom, or a blood bank. PharmaWatch uses patented Virtual Temperature Buffering™ (VTB™) to model actual product temperature algorithmically — no physical object in your storage environment, ever.

Calibration That Never Interrupts Monitoring

Most systems require a service visit when calibration is due — meaning a technician, a scheduling delay, and a gap in your monitoring record. PharmaWatch ships a pre-calibrated probe to you before expiration. Swap it in 60 seconds. The record stays continuous.

One Dashboard. Every Freezer. Every Location.

PharmaWatch data flows to a single portal regardless of how many units or sites you have. Current status, trend charts, compliance reports, calibration certificates — all accessible in three clicks, on any device, from anywhere.

Automated Compliance

Automate Your Compliance

Joint Commission surveyors, FDA inspectors, State Board of Pharmacy auditors — they all want to see the same thing: continuous, documented proof that your medication and blood product storage has been monitored and is within spec. Manual paper logs create exactly the gaps they’re looking for. PharmaWatch eliminates them entirely.

Every temperature reading is logged automatically with a timestamp. Every alarm is documented with an acknowledgment and resolution note. Every door open event is on record. Pull a complete compliance report for any refrigerator or freezer in 3 clicks — for any time range, any regulatory body, any inspection.

A white device labeled "PharmaWatch" with an antenna at the top is centrally placed. Surrounding it are icons representing a shield for security, documents with checkmarks, and a computer screen displaying a graph. The background is light gray.

Frequently ask a questions

Find the answers here

What temperature ranges does PharmaWatch monitor for refrigerators and freezers?
PharmaWatch monitors across the full spectrum of healthcare cold storage — standard refrigerators at 2–8°C, medication and plasma freezers from –15°C to –50°C, and ultra-low freezers down to –86°C. Alarm thresholds are fully customizable to your specific storage requirements and regulatory standards.
Does PharmaWatch work without WiFi?
Yes — and that's the point. PharmaWatch transmits over cellular (Verizon, AT&T, and T-Mobile) and never touches your hospital or pharmacy network. No credentials, no firewall changes, no IT involvement. It keeps reporting during outages, IT maintenance windows, and cyberattacks — backed by a 5-day battery.
What compliance standards does PharmaWatch support for refrigerator and freezer monitoring?
PharmaWatch supports compliance with FDA 21 CFR Part 11, FDA GxP/cGMP/GLP, USP 797/800 for sterile compounding, CDC/VFC vaccine storage requirements, State Board of Pharmacy requirements, AABB accreditation requirements, and Joint Commission temperature monitoring requirements. IQ/OQ/PQ validation is included in every deployment — not sold separately.
Why does it matter that there are no physical buffers in the freezer?
Physical glycol buffers sitting next to your sensor are a contamination risk in sterile environments — pharmacies, cleanrooms, blood banks. PharmaWatch's patented Virtual Temperature Buffering™ (VTB™) eliminates them entirely, modeling product temperature algorithmically. No maintenance, no contamination risk, and the raw signal stays intact for predictive analytics.
How does calibration work for freezer and refrigerator monitoring?
PharmaWatch uses a replaceable probe architecture — individually serialized, ISO 17025 pre-calibrated probes that you swap yourself in under 60 seconds. A new probe ships automatically before your NIST expiration date. No service visit, no monitoring gap, no scheduling.
Can PharmaWatch alert us before a freezer actually fails?
Yes. Because VTB™ preserves the raw air temperature signal, PharmaWatch's predictive analytics detect early equipment degradation — compressor cycling more frequently, recovery times increasing — before temperatures ever go out of range. You get a maintenance alert, not a product loss.
What happens if the power goes out?
The sensor radio has a 5-day battery backup. Monitoring continues uninterrupted, data stores locally, and when power is restored everything forwards to the portal automatically. No gap in the record.
Can PharmaWatch monitor multiple fridges and freezers across different locations?
Yes. The portal gives you a single view across every unit at every location — current temps, alert history, compliance records, and calibration status. Adding a new site requires zero network coordination. Plug in a sensor and it appears on your dashboard.
