Vaisala DL1000, DL1400, DL1016 and DL1416 Temperature Data Loggers
Product lifecycle notice: The DL1000, DL1400, DL1016 and DL1416 series are scheduled for future discontinuation. Confirm availability before specifying them for a new project. For new continuous-monitoring systems, consider the Vaisala VDL200 with suitable smart probes.
The Vaisala DL1000 and DL1400 series are precision temperature data loggers for continuous monitoring and validation work. Available with two or four channels and a choice of internal or external sensors, they can cover applications ranging from warehouses and incubators to ultra-low-temperature freezers.
The DL1016 and DL1416 are the external-probe configurations. The DL1016 provides two external channels, while the DL1416 provides four, allowing one logger to monitor several cabinets, chambers or measurement positions.
When connected to the Vaisala viewLinc Continuous Monitoring System, the loggers provide historical and real-time data, remote alarms and controlled reporting. They can also be used with Vaisala vLog for validation and mapping.
| At a Glance | DL1000–DL1416 Series |
|---|---|
| Channel configurations | 2 or 4 channels, depending on model |
| External-probe calibrated ranges | −25 to +70 °C with N-range probes; −90 to −40 °C with V-range probes |
| Recording | Autonomous onboard memory with user-selectable sampling intervals |
| Power | Internal lithium battery with a typical 10-year life at intervals of one minute or longer |
Current Replacement Platform: Vaisala VDL200
The Vaisala VDL200 is the current replacement platform for many DL1000, DL1400, DL1016 and DL1416 continuous-monitoring applications. It uses interchangeable smart probes and a native Ethernet or Power over Ethernet connection to the viewLinc system.
| Consideration | Legacy DL1000–DL1416 Series | Current VDL200 Platform |
|---|---|---|
| Product generation | DL-series platform approaching phase-out | Current-generation viewLinc data logger |
| Measurement arrangement | Internal or fixed channel-specific temperature configuration | Interchangeable smart probes selected for the application |
| Channels | Two- or four-channel configurations | Up to two probe ports and multiple recorded parameters, depending on probe selection |
| Network connection | RS-232 with optional USB, Ethernet, PoE or Wi-Fi interface | Native Ethernet and Power over Ethernet with battery backup |
| Migration requirement | Existing systems may remain in service | Probe range, channel quantity, cabling, network and viewLinc compatibility must be checked |
Not always a direct one-for-one replacement: DL1416 installations may use four external temperature channels, while one VDL200 has two probe ports. Confirm the number of measurement points and required temperature range when planning the migration.
Choosing the Correct Logger
| Model Family | Configuration | Suitable Applications |
|---|---|---|
| DL1000 | Two-channel platform with internal and external sensor configurations | Single cabinets, rooms and equipment requiring one or two measurement points |
| DL1400 | Four-channel platform with internal and external sensor configurations | Several measurement points located close together |
| DL1016 | Two external V-range temperature channels | Two freezers, refrigerators or external probe positions |
| DL1416 | Four external V-range temperature channels | Multi-application monitoring or mapping with up to four probes |
Model selection: The exact channel arrangement, probe range and VL or SP software configuration must be confirmed when ordering. Seacom can check the complete model code against the application.
Temperature Probe Options
| Sensor Option | Calibrated Range | Typical Application |
|---|---|---|
| Internal sensor | −25 to +70 °C | Rooms, warehouses and chambers where the complete logger can be installed at the measurement point |
| N-range external probe | −25 to +70 °C | Refrigerators, incubators and general temperature monitoring |
| V-range external probe | −90 to −40 °C | Ultra-low-temperature freezers and other low-temperature equipment |
External probes are calibrated with their assigned logger channel. Keep each probe paired with the correct channel to maintain the stated system accuracy.
Why Record at the Measurement Point?
- Protection from network interruptions: Measurements continue to be stored in the logger if the network connection is interrupted.
- Protection from mains-power failures: The internal battery allows autonomous recording without relying on local AC power.
- Gap-free records: Stored measurements can be transferred to viewLinc when communication is restored.
- Long recording periods: Sampling intervals can be adjusted according to the monitoring or mapping requirement.
Typical Applications
- Ultra-low-temperature freezers: External V-range probes provide calibrated measurement down to −90 °C.
- Refrigerators and freezers: External probes allow the logger body to remain outside the cabinet.
- Incubators: Stable temperature monitoring with traceable calibration.
- Cold rooms and warehouses: Continuous recording, alarming and reporting through viewLinc.
- Validation and mapping: Two- or four-channel configurations reduce the number of loggers needed for a study.
- Door monitoring: Selected configurations support Boolean inputs for a door switch or alarm contact.
viewLinc and vLog Software
| Software | Purpose |
|---|---|
| viewLinc Enterprise Server | Continuous monitoring, remote alarms, audit trails, access control and reporting |
| vLog VL | Validation and mapping for GxP-regulated applications |
| vLog SP | Graphing and reporting for non-GxP applications |
| OPC integration | Makes compatible live or historical monitoring data available to third-party systems |
The complete viewLinc system can support records and workflows designed to meet FDA 21 CFR Part 11 and EU GMP Annex 11 requirements. Compliance depends on the complete system configuration, validation and operating procedures.
