Features :
- Compact housing
- Short stabilization time
- User friendly operation
- ALE provides three advantages as key values. ALE series is new answer to optimized weighing operation in the laboratory.
Tuning-fork sensor inside, Only one in the world
As tuning-fork sensor balance, ALE series provides incomparable advantages to laboratory weighing. Sustainable high quality performance. High durability in the long run. Since these are inherent in the principle and the design of tuning-fork sensor, the customers can enjoy the advantages even in highly precise laboratory weighing operation. Vibra ALE8201R Precision Balance
Compact housing
The smallest footprint among precision balances. You can install the balance wherever you want, even in very small laboratory.
Short stabilization time
ALE has newly developed filtering technology which can reduces the stabilization time to the half of the previous models. Short stabilization time is key factor to efficient weighing operation.\
Windshield in innovative design
Innovative windshield strikes a good balance between space-saving design and easy access to weighing chamber.
Easy to clean
Windshield can be easily removed manually. Convenient for the users to clean the balance after daily operation.
Extremely durable against strong impact
ALE series is designed to be very durable against strong impact. Even when heavy objects would accidentally fall down on the balance during operation, ALE can absorb the physical shock. You can resume the weighing operation immediately.
Minimize operation time with free keys
Three keys on the front can work as free keys. You can assign short-cut of often used functions on these keys. You don’t need to push keys many times. It can minimize the operation time.
Battery drive
ALE can be operated with dry-cell batteries thanks to low power consumption in tuning-fork sensor. Battery is useful also as reserve electric power.

Timbangan analitik adalah kelas timbangan yang dirancang untuk mengukur massa kecil dalam kisaran sub-miligram. papan pengukur timbangan analitik (0,1 mg atau lebih baik) berada di dalam selungkup transparan berpintu sehingga debu tidak terkumpul sehingga arus udara di ruangan tidak memengaruhi operasi timbangan. Enklosur ini sering disebut draft shield. Penggunaan selungkup pengaman timbangan berventilasi mekanis, yang memiliki airfoil akrilik yang dirancang secara unik, memungkinkan aliran udara bebas turbulensi yang mulus yang mencegah fluktuasi keseimbangan dan ukuran massa hingga 1 μg tanpa fluktuasi atau kehilangan produk. Selain itu, sampel harus pada suhu kamar untuk mencegah konveksi alami dari pembentukan arus udara di dalam enklosur yang menyebabkan kesalahan dalam pembacaan. Keseimbangan substitusi mekanis panci tunggal mempertahankan respons yang konsisten sepanjang kapasitas yang berguna dicapai dengan mempertahankan beban konstan pada balok keseimbangan, sehingga titik tumpu, dengan mengurangi massa pada sisi yang sama dari balok tempat sampel ditambahkan.
Skala analistik elektronik mengukur gaya yang dibutuhkan untuk melawan massa yang sedang diukur daripada menggunakan massa sebenarnya. Karena itu, mereka harus memiliki penyesuaian kalibrasi untuk mengimbangi perbedaan gravitasi. Mereka menggunakan elektromagnet untuk menghasilkan gaya untuk melawan sampel yang sedang diukur dan mengeluarkan hasilnya dengan mengukur gaya yang diperlukan untuk mencapai keseimbangan. Alat pengukur seperti itu disebut sensor pemulihan gaya elektromagnetik.
Di Mesir, timbangan dapat ditelusuri hingga sekitar tahun 1878 SM, tetapi penggunaannya mungkin jauh lebih awal. Batu berukir dengan tanda yang menunjukkan massa dan simbol hieroglif Mesir untuk emas telah ditemukan, yang menunjukkan bahwa pedagang Mesir telah menggunakan sistem pengukuran massa yang mapan untuk membuat katalog pengiriman emas atau hasil tambang emas. Meskipun tidak ada timbangan sebenarnya dari era ini yang bertahan, banyak set batu timbangan serta mural yang menggambarkan penggunaan timbangan timbangan menunjukkan penggunaan yang meluas. Di Tiongkok, timbangan paling awal yang digali berasal dari makam Negara Chu dari Zaman Perang Tiongkok yang berasal dari abad ke-3 hingga ke-4 SM di Gunung Zuojiagong dekat Changsha, Hunan. Keseimbangannya terbuat dari kayu dan menggunakan massa perunggu.
