B4100 Bluetooth Digital Thermometer：

Precision Health Monitoring for Babies and Beyond

The B4100 is a next-generation medical-grade Bluetooth thermometer designed to give you real-time, ultra-precise temperature insights—especially when caring for infants, children, and elderly patients.

±0.1°C Medical Accuracy, Right Where It Counts

Unlike traditional thermometers, the B4100 offers ±0.1°C accuracy in the critical 35°C to 42°C range—essential for detecting early signs of fever in babies and vulnerable patients.

Its high-precision NTC thermistor captures even the most subtle temperature fluctuations, giving you clarity when it matters most.

IPX7 Waterproof, Built for Real Life

Encased in medical-grade, biocompatible ABS plastic and sealed to IPX7 standards, the B4100 is fully submersible up to 1 meter. From baby baths to accidental drops—it’s ready.

And at just 10 mm thin, it’s lightweight enough to wear all day, whether under an armpit, on the abdomen, or even as a veterinary ear tag.

Bluetooth 5.0 with Real-Time Alerts

The B4100 connects via Bluetooth 5.0 BLE for stable, low-energy transmission over 10+ meters.

No more guesswork. The mobile app provides:

• Real-time temperature graphing
• Custom alertsfor fevers (e.g. >37.5°C
• Medication reminders
• Secure data export & cloud sync

With AES-128 encrypted transmission and FDA-compliant cybersecurity, your family’s health data stays private and protected.

Stay Connected, Even While They Sleep

The B4100 supports hands-free monitoring—ideal for babies, toddlers, and anyone resting. The 1.5″ tri-color LCD automatically lights up to indicate temperature status:

• Green: Normal
• Yellow: Slightly elevated
• Red: High fever

You’ll know the moment something changes—without waking them up.

Built for Home or Clinic Use

Whether you’re a parent, caregiver, or medical professional, the B4100 adapts to your needs:

• At Home:Daily health tracking for babies, kids, and seniors
• In Clinics:Continuous monitoring for patients
• Remote Care:Post-op recovery or eldercare support
• Veterinary Use:Ear tag mode for livestock or pets

What makes B4100 different from other thermometers?

The B4100 solves common pain points of traditional thermometers with key upgrades:

• Higher accuracy: ±0.1°C in 35°C–42°C (vs. ±0.2°C or lower in peers).
• Better connectivity: Bluetooth 5.0 BLE (≥10m range) for stable, long-distance syncing (vs. limited Bluetooth 4.0/4.2).
• Smart tracking: Real-time data logging, remote alerts, and cloud storage (optional) (vs. no data history or local-only displays).
• Durability: IPX7 waterproof, medical-grade ABS plastic (ISO 10993-1), and 1m drop resistance (IEC 60601-1 compliant).

Is B4100 safe for babies?

Yes! The B4100 is designed with infants and children in mind:

• Skin-safe materials: Made of medical-grade ABS plastic, tested to ISO 10993-1 biocompatibility standards (gentle on sensitive skin).
• Non-invasive design: Smooth edges and lightweight (120×25×10 mm) for comfortable armpit, forehead, or navel placement.
• Waterproof: IPX7 rating (submersible up to 1m for 30 minutes) makes cleaning easy with 75% isopropyl alcohol wipes.

How does the Bluetooth 5.0 connection work for baby monitoring?

Bluetooth 5.0 BLE enables:

• Long range: Syncs data to your phone from ≥10 meters away—monitor your sleeping baby from another room without disturbing them.
• Real-time alerts: Abnormal temperatures trigger on-device LED/audio alarms and phone push notifications (customizable thresholds, e.g., ≥37.5°C).
• Security: AES-128 encrypted transmission, compliant with FDA cybersecurity standards to protect your baby’s health data.

How long does the battery last, and when should I replace it?

The B4100 uses a CR2032 coin cell battery with:

• Battery life: ≥6 months with 10 uses per day (auto-shuts off after 10 seconds to save power).
• Low-battery alert: A yellow LED flash and buzzer notify you when the battery voltage drops below 2.6V—replace it promptly to avoid interruptions.

Can I track fever trends and share data with my pediatrician?

Yes! The B4100 app offers:

• Graph-based history: Visualize temperature trends over hours/days to spot patterns.
• Event logging: Note medication times, cooling measures, or symptoms.
• Data export: Export reports in CSV/Excel format to share with healthcare providers for better diagnosis and care.

Does B4100 require calibration?

Yes, for consistent accuracy:

• Calibration schedule: Recalibrate every 6 months using a constant-temperature bath.
• Method: Supports dual-point calibration (0°C and 100°C) and up to 300 calibrations over its lifespan.

What certifications does B4100 have?

The B4100 is certified to global medical standards:

• FDA 510(k)
• CE (EN standards)
• ISO 13485 (medical device quality management)
• Bluetooth SIG (wireless compliance)

Can B4100 be used for more than baby care?

Absolutely! It’s versatile for:

• Home use: Adults, children, and infants.
• Clinical settings: Clinics, hospitals, and chronic condition management.
• Remote tracking: Elderly care or post-surgery recovery.
• Livestock monitoring: Ear tag use for epidemic tracing and temperature tracking.
