Group3高斯计/特斯拉计优点：

1. 高精度

2. 高分辨率

3. 小尺寸探头

4. 可覆盖全量程的探头

5. 抗干扰

6. 可更换探头

Group3高斯计/特斯拉计是精度最高的霍尔效应的磁场测试仪器，同价位仪器中没有可与之相比的精度。Group3特有的线性和温度补偿技术克服了霍尔元件固有的缺陷。Group3的每一个探头都是独特的，其校准系数数据由计算机计算后存储在探头自带芯片中。先进的算法确保了特斯拉计的测量准确性。

没有其他磁场测试仪器的温度稳定性可以达到DTM-151(LPT-141)特斯拉的10ppm/℃，一般情况都达不到一半。

探头中极小的霍尔片非常适合测绘磁场。Group3高斯计/特斯拉计最特别的优势是测量不均匀区域的磁场，测试时探头移到需要测试区域即可，也适合测量交变磁场。Group3的高精度的高斯计/特斯拉计与核磁共振有相近的分辨率和应用，但是费用却远低于核磁共振测试系统。

由于探头的特征信息数据保存在探头内部芯片上使得任一探头可以与任一主机相适配，并保证了测试精度和准确度。探头的量程范围更为宽广，测试时可不再更换探头。可根据测量对象的不同、分辨率要求及温度补偿等选择探头。

磁场测试数据通过7段数码LED显示，在正常的实验室、昏暗、明亮的环境下均可清晰可见。

Group3高斯计/特斯拉计的前面板很简单，只有两个按键。Group3采用的是一种简洁的方法而不是给每一个功能都增加一个按键。

先进的驱动方法使探头和主机之间的电缆长度被大大延长，最长可达30米。
