Vaisala DL1000, DL1400, DL1016 and DL1416 Temperature Data Loggers
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.
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.
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 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
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
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.
Key Technical Specifications
Which Vaisala Data Logger?
Vaisala Temperature Data Logger Supplier and System Integrator in Malaysia
Seacom Process Instruments supplies and supports Vaisala DL1000, DL1400, DL1016 and DL1416 temperature data loggers in Malaysia for pharmaceutical facilities, laboratories, hospitals, blood banks, warehouses, cold rooms, refrigerators, incubators and ultra-low-temperature freezers. We can also assist existing DL-series users with migration planning for the VDL200 platform.
Our team can assist with model and probe selection, monitoring-point planning, thermal-buffer selection, network connectivity, viewLinc system integration, installation, commissioning, alarm configuration, calibration planning and GxP validation documentation.
Contact Seacom with your temperature range, required accuracy, number of channels, probe length, door-contact requirement, sampling interval, network constraints and validation expectations. We can check whether a DL-series logger is still appropriate or prepare a suitable VDL200 configuration.
