Series 390 HF/HA Semi-Micro
& Analytical Balances

If you want to be prepared for all weighing challenges, choose the comprehensive HF model. It is the top of the range, with all Precisa’s high-end technologies. They have touchless sensors which are programmed with different functions including contactless draft shield opening, tare, print and other useful functions.

The various applications make daily work easier and work perfectly together with the Electrostatic Cancellation System (ECS) and Ambient Observation System (AOS). ECS and AOS ensure the most reliable weighing results under all conditions and with traceability. The HF’s weighing is at the peak of available technology.

The HA model is the complete 390 series analytical balance and you can easily upgrade the machine with all available accessories. With the automated draft shield already installed, and the full set of applications, this smart design simplifies weighing. This high-end instrument can easily be upgraded at any time with ECS and AOS systems by a Precisa trained service engineer.

Precisa balances are prime examples of Swiss precision, accuracy, and reliability.

They are tried and tested in both demanding laboratory environments and industrial applications and are subject to rigorous quality controls throughout the entire manufacturing process. Precisa invests continuously in developing new technologies and the result is a state-of-the-art range of precision instruments for the most exacting demands.

User Management

Your analytical balance can be set and optimized for various users by using the built-in, extensive user management system.

A user profile is set just once so when a user begins to work with the balance, just choose the correct profile and the balance is ready the way the user needs it, personalized with broad access rights, or just set with the basic operation facilities, like right- or left-handed user.

Touchless Sensor

The touchless sensors are very helpful when you perform daily routines with your analytical balances, like opening a draft shield door, taring or zeroing the balance or performing a special function.

You can set the built-in touchless sensors to activate those functions by a simple hand motion. The sensors can be adjusted with three detection angles to follow your own, personal needs and tasks.

It is possible to easily upgrade balances which are not fitted with this feature at a later stage.

Electrostatic
Cancellation System

All electrostatic charges are neutralized quickly by our built-in AC pulse technique utilizing an ion neutralizing system, which is engineered and manufactured together with Panasonic.

Operation is effortless. Just by placing the sample into the weighing chamber, your sample is automatically neutralized when the draft shield is closed. No laborious search for an externally installed ionizer. Retrofit installation of an ECS is possible by a local Precisa engineer.

Ambient
Observation System

Various ambient air conditions affect the weighing result. Therefore, meteorological factors such as air pressure, air humidity and air temperature are recorded with AOS. This is done in real time and inside the weighing chamber where the sample is placed.

This important parameter supports the traceability and can also provide an indication of the ambient status. The information can be recorded, used just as an indication or as an additional parameter when calculating the weighing result with the BEST app.

Communication & Interfaces

The 390 series weighing scales are ready to satisfy your communication needs with seamless connectivity, whether you are already working in a paperless lab with LIMS or not. We have equipped the balance with all the standard interfaces that are common today:

2 x USB type A (host)
1 x USB type B (device)
1 x 100M Ethernet

On the rear of the balance an RS232 and USB type B interface are included. Therefore, connecting your analytical balance to a PC or RS232 printer for protocol printout is easy and efficient. Additional interfaces such as WiFi, Bluetooth etc. are available as accessories.
